-### Contributing code
-
-You can have a huge impact on the project by helping with its code. To contribute code to Caddy, first submit or comment in an issue to discuss your contribution, then open a [pull request](https://github.com/caddyserver/caddy/pulls) (PR). If you're new to our community, that's okay: **we gladly welcome pull requests from anyone, regardless of your native language or coding experience.** You can get familiar with Caddy's code base by using [code search at Sourcegraph](https://sourcegraph.com/github.com/caddyserver/caddy).
-
-We hold contributions to a high standard for quality :bowtie:, so don't be surprised if we ask for revisions—even if it seems small or insignificant. Please don't take it personally. :blue_heart: If your change is on the right track, we can guide you to make it mergable.
-
-Here are some of the expectations we have of contributors:
-
-- **Open an issue to propose your change first.** This way we can avoid confusion, coordinate what everyone is working on, and ensure that any changes are in-line with the project's goals and the best interests of its users. We can also discuss the best possible implementation. If there's already an issue about it, comment on the existing issue to claim it. A lot of valuable time can be saved by discussing a proposal first.
-
-- **Keep pull requests small.** Smaller PRs are more likely to be merged because they are easier to review! We might ask you to break up large PRs into smaller ones. [An example of what we want to avoid.](https://twitter.com/iamdevloper/status/397664295875805184)
-
-- **Keep related commits together in a PR.** We do want pull requests to be small, but you should also keep multiple related commits in the same PR if they rely on each other.
-
-- **Write tests.** Good, automated tests are very valuable! Written properly, they ensure your change works, and that other changes in the future won't break your change. CI checks should pass.
-
-- **Benchmarks should be included for optimizations.** Optimizations sometimes make code harder to read or have changes that are less than obvious. They should be proven with benchmarks and profiling.
-
-- **[Squash](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html) insignificant commits.** Every commit should be significant. Commits which merely rewrite a comment or fix a typo can be combined into another commit that has more substance. Interactive rebase can do this, or a simpler way is `git reset --soft <diverging-commit>` then `git commit -s`.
-
-- **Be responsible for and maintain your contributions.** Caddy is a growing project, and it's much better when individual contributors help maintain their change after it is merged.
-
-- **Use comments properly.** We expect good godoc comments for package-level functions, types, and values. Comments are also useful whenever the purpose for a line of code is not obvious.
-
-- **Pull requests may still get closed.** The longer a PR stays open and idle, the more likely it is to be closed. If we haven't reviewed it in a while, it probably means the change is not a priority. Please don't take this personally, we're trying to balance a lot of tasks! If nobody else has commented or reacted to the PR, it likely means your change is useful only to you. The reality is this happens quite a lot. We don't tend to accept PRs that aren't generally helpful. For these reasons or others, the PR may get closed even after a review. We are not obligated to accept all proposed changes, even if the best justification we can give is something vague like, "It doesn't sit right." Sometimes PRs are just the wrong thing or the wrong time. Because it is open source, you can always build your own modified version of Caddy with a change you need, even if we reject it in the official repo. Plus, because Caddy is extensible, it's possible your feature could make a great plugin instead!
-
-- **You certify that you wrote and comprehend the code you submit.** The Caddy project welcomes original contributions that comply with [our CLA](https://cla-assistant.io/caddyserver/caddy), meaning that authors must be able to certify that they created or have rights to the code they are contributing. In addition, we require that code is not simply copy-pasted from Q/A sites or AI language models without full comprehension and rigorous testing. In other words: contributors are allowed to refer to communities for assistance and use AI tools such as language models for inspiration, but code which originates from or is assisted by these resources MUST be:
-
-	- Licensed for you to freely share
-	- Fully comprehended by you (be able to explain every line of code)
-	- Verified by automated tests when feasible, or thorough manual tests otherwise
-
-	We have found that current language models (LLMs, like ChatGPT) may understand code syntax and even problem spaces to an extent, but often fail in subtle ways to convey true knowledge and produce correct algorithms. Integrated tools such as GitHub Copilot and Sourcegraph Cody may be used for inspiration, but code generated by these tools still needs to meet our criteria for licensing, human comprehension, and testing. These tools may be used to help write code comments and tests as long as you can certify they are accurate and correct. Note that it is often more trouble than it's worth to certify that Copilot (for example) is not giving you code that is possibly plagiarised, unlicensed, or licensed with incompatible terms -- as the Caddy project cannot accept such contributions. If that's too difficult for you (or impossible), then we recommend using these resources only for inspiration and write your own code. Ultimately, you (the contributor) are responsible for the code you're submitting.
-
-	As a courtesy to reviewers, we kindly ask that you disclose when contributing code that was generated by an AI tool or copied from another website so we can be aware of what to look for in code review.
-
-We often grant [collaborator status](#collaborator-instructions) to contributors who author one or more significant, high-quality PRs that are merged into the code base.

-#### HOW TO MAKE A PULL REQUEST TO CADDY
-
-Contributing to Go projects on GitHub is fun and easy. After you have proposed your change in an issue, we recommend the following workflow:
-
-1. [Fork this repo](https://github.com/caddyserver/caddy). This makes a copy of the code you can write to.
-
-2. If you don't already have this repo (caddyserver/caddy.git) repo on your computer, clone it down: `git clone https://github.com/caddyserver/caddy.git`
-
-3. Tell git that it can push the caddyserver/caddy.git repo to your fork by adding a remote: `git remote add myfork https://github.com/<your-username>/caddy.git`
-
-4. Make your changes in the caddyserver/caddy.git repo on your computer.
-
-5. Push your changes to your fork: `git push myfork`
-
-6. [Create a pull request](https://github.com/caddyserver/caddy/pull/new/master) to merge your changes into caddyserver/caddy @ master. (Click "compare across forks" and change the head fork.)
-
-This workflow is nice because you don't have to change import paths. You can get fancier by using different branches if you want.
-
-
-### Writing a Caddy module
-
-Caddy can do more with modules! Anyone can write one. Caddy modules are Go libraries that get compiled into Caddy, extending its feature set. They can add directives to the Caddyfile, add new configuration adapters, and even implement new server types (e.g. HTTP, DNS).
-
-[Learn how to write a module here](https://caddyserver.com/docs/extending-caddy). You should also share and discuss your module idea [on the forums](https://caddy.community) to have people test it out. We don't use the Caddy issue tracker for third-party modules.
-
-
-### Getting help using Caddy
-
-If you have a question about using Caddy, [ask on our forum](https://caddy.community)! There will be more people there who can help you than just the Caddy developers who follow our issue tracker. Issues are not the place for usage questions.
-
-Many people on the forums could benefit from your experience and expertise, too. Once you've been helped, consider giving back by answering other people's questions and participating in other discussions.
-
-
-### Reporting bugs
-
-Like every software, Caddy has its flaws. If you find one, [search the issues](https://github.com/caddyserver/caddy/issues) to see if it has already been reported. If not, [open a new issue](https://github.com/caddyserver/caddy/issues/new) and describe the bug, and somebody will look into it! (This repository is only for Caddy and its standard modules.)
-
-**You can help us fix bugs!** Speed up the patch by identifying the bug in the code. This can sometimes be done by adding `fmt.Println()` statements (or similar) in relevant code paths to narrow down where the problem may be. It's a good way to [introduce yourself to the Go language](https://tour.golang.org), too.
-
-We may reply with an issue template. Please follow the template so we have all the needed information. Unredacted&mdash;yes, actual values matter. We need to be able to repeat the bug using your instructions. Please simplify the issue as much as possible. If you don't, we might close your report. The burden is on you to make it easily reproducible and to convince us that it is actually a bug in Caddy. This is easiest to do when you write clear, concise instructions so we can reproduce the behavior (even if it seems obvious). The more detailed and specific you are, the faster we will be able to help you!
-
-We suggest reading [How to Report Bugs Effectively](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html).
-
-Please be kind. :smile: Remember that Caddy comes at no cost to you, and you're getting free support when we fix your issues. If we helped you, please consider helping someone else!
-
-#### Bug reporting expectations
-
-Maintainers---or more generally, developers---need three things to act on bugs:
-
-1. To agree or be convinced that it's a bug (reporter's responsibility).
-	- A bug is unintentional, undesired, or surprising behavior which violates documentation or relevant spec. It might be either a mistake in the documentation or a bug in the code.
-	- This project usually does not work around bugs in other software, systems, and dependencies; instead, we recommend that those bugs are fixed at their source. This sometimes means we close issues or reject PRs that attempt to fix, workaround, or hide bugs in other projects.
-
-2. To be able to understand what is happening (mostly reporter's responsibility).
-	- If the reporter can provide satisfactory instructions such that a developer can reproduce the bug, the developer will likely be able to understand the bug, write a test case, and implement a fix. This is the least amount of work for everyone and path to the fastest resolution.
-	- Otherwise, the burden is on the reporter to test possible solutions. This is less preferable because it loosens the feedback loop, slows down debugging efforts, obscures the true nature of the problem from the developers, and is unlikely to result in new test cases.
-
-3. A solution, or ideas toward a solution (mostly maintainer's responsibility).
-	- Sometimes the best solution is a documentation change.
-	- Usually the developers have the best domain knowledge for inventing a solution, but reporters may have ideas or preferences for how they would like the software to work.
-	- Security, correctness, and project goals/vision all take priority over a user's preferences.
-	- It's simply good business to yield a solution that satisfies the users, and it's even better business to leave them impressed.
-
-Thus, at the very least, the reporter is expected to:
-
-1. Convince the reader that it's a bug in Caddy (if it's not obvious).
-2. Reduce the problem down to the minimum specific steps required to reproduce it.
-
-The maintainer is usually able to do the rest; but of course the reporter may invest additional effort to speed up the process.
-
-
-
-### Suggesting features
-
-First, [search to see if your feature has already been requested](https://github.com/caddyserver/caddy/issues). If it has, you can add a :+1: reaction to vote for it. If your feature idea is new, open an issue to request the feature. Please describe your idea thoroughly so that we know how to implement it! Really vague requests may not be helpful or actionable and, without clarification, will have to be closed.
-
-While we really do value your requests and implement many of them, not all features are a good fit for Caddy. Most of those [make good modules](#writing-a-caddy-module), which can be made by anyone! But if a feature is not in the best interest of the Caddy project or its users in general, we may politely decline to implement it into Caddy core. Additionally, some features are bad ideas altogether (for either obvious or non-obvious reasons) which may be rejected. We'll try to explain why we reject a feature, but sometimes the best we can do is, "It's not a good fit for the project."
-
-
-### Improving documentation
-
-Caddy's documentation is available at [https://caddyserver.com/docs](https://caddyserver.com/docs) and its source is in the [website repo](https://github.com/caddyserver/website). If you would like to make a fix to the docs, please submit an issue there describing the change to make.
-
-Note that third-party module documentation is not hosted by the Caddy website, other than basic usage examples. They are managed by the individual module authors, and you will have to contact them to change their documentation.
-
-Our documentation is scoped to the Caddy project only: it is not for describing how other software or systems work, even if they relate to Caddy or web servers. That kind of content [can be found in our community wiki](https://caddy.community/c/wiki/13), however.
-
-## Collaborator Instructions
-
-Collaborators have push rights to the repository. We grant this permission after one or more successful, high-quality PRs are merged! We thank them for their help. The expectations we have of collaborators are:
-
-- **Help review pull requests.** Be meticulous, but also kind. We love our contributors, but we critique the contribution to make it better. Multiple, thorough reviews make for the best contributions! Here are some questions to consider:
-	- Can the change be made more elegant?
-	- Is this a maintenance burden?
-	- What assumptions does the code make?
-	- Is it well-tested?
-	- Is the change a good fit for the project?
-	- Does it actually fix the problem or is it creating a special case instead?
-	- Does the change incur any new dependencies? (Avoid these!)
-
-- **Answer issues.** If every collaborator helped out with issues, we could count the number of open issues on two hands. This means getting involved in the discussion, investigating the code, and yes, debugging it. It's fun. Really! :smile: Please, please help with open issues. Granted, some issues need to be done before others. And of course some are larger than others: you don't have to do it all yourself. Work with other collaborators as a team!
-
-- **Do not merge pull requests until they have been approved by one or two other collaborators.** If a project owner approves the PR, it can be merged (as long as the conversation has finished too).
-
-- **Prefer squashed commits over a messy merge.** If there are many little commits, please [squash the commits](https://stackoverflow.com/a/11732910/1048862) so we don't clutter the commit history.
-
-- **Don't accept new dependencies lightly.** Dependencies can make the world crash and burn, but they are sometimes necessary. Choose carefully. Extremely small dependencies (a few lines of code) can be inlined. The rest may not be needed. For those that are, Caddy uses [go modules](https://github.com/golang/go/wiki/Modules). All external dependencies must be installed as modules, and _Caddy must not export any types defined by those dependencies_. Check this diligently!
-
-- **Be extra careful in some areas of the code.** There are some critical areas in the Caddy code base that we review extra meticulously: the `caddyhttp` and `caddytls` packages especially.
-
-- **Make sure tests test the actual thing.** Double-check that the tests fail without the change, and pass with it. It's important that they assert what they're purported to assert.
-
-- **Recommended reading**
-	- [CodeReviewComments](https://github.com/golang/go/wiki/CodeReviewComments) for an idea of what we look for in good, clean Go code
-	- [Linus Torvalds describes a good commit message](https://gist.github.com/matthewhudson/1475276)
-	- [Best Practices for Maintainers](https://opensource.guide/best-practices/)
-	- [Shrinking Code Review](https://alexgaynor.net/2015/dec/29/shrinking-code-review/)
-
-
-
-## Values (WIP)
-
-- A person is always more important than code. People don't like being handled "efficiently". But we can still process issues and pull requests efficiently while being kind, patient, and considerate.
-
-- The ends justify the means, if the means are good. A good tree won't produce bad fruit. But if we cut corners or are hasty in our process, the end result will not be good.
-

-## Security Policy

-If you think you've found a security vulnerability, please refer to our [Security Policy](https://github.com/caddyserver/caddy/security/policy) document.

-# Security Policy
-
-The Caddy project would like to make sure that it stays on top of all practically-exploitable vulnerabilities.
-
-

-
-## Acceptable Scope
-
-A security report must demonstrate a security bug in the source code from this repository.
-
-Some security problems are the result of interplay between different components of the Web, rather than a vulnerability in the web server itself. Please only report vulnerabilities in the web server itself, as we cannot coerce the rest of the Web to be fixed (for example, we do not consider IP spoofing, BGP hijacks, or missing/misconfigured HTTP headers a vulnerability in the Caddy web server).
-
-Vulnerabilities caused by misconfigurations are out of scope. Yes, it is entirely possible to craft and use a configuration that is unsafe, just like with every other web server; we recommend against doing that.
-
-We do not accept reports if the steps imply or require a compromised system or third-party software, as we cannot control those. We expect that users secure their own systems and keep all their software patched. For example, if untrusted users are able to upload/write/host arbitrary files in the web root directory, it is NOT a security bug in Caddy if those files get served to clients; however, it _would_ be a valid report if a bug in Caddy's source code unintentionally gave unauthorized users the ability to upload unsafe files or delete files without relying on an unpatched system or piece of software.
-
-Client-side exploits are out of scope. In other words, it is not a bug in Caddy if the web browser does something unsafe, even if the downloaded content was served by Caddy. (Those kinds of exploits can generally be mitigated by proper configuration of HTTP headers.) As a general rule, the content served by Caddy is not considered in scope because content is configurable by the site owner or the associated web application.
-
-Security bugs in code dependencies (including Go's standard library) are out of scope. Instead, if a dependency has patched a relevant security bug, please feel free to open a public issue or pull request to update that dependency in our code.
-
-
-## Reporting a Vulnerability
-
-We get a lot of difficult reports that turn out to be invalid. Clear, obvious reports tend to be the most credible (but are also rare).
-
-First please ensure your report falls within the accepted scope of security bugs (above).
-
-We'll need enough information to verify the bug and make a patch. To speed things up, please include:
-
-- Most minimal possible config (without redactions!)
-- Command(s)
-- Precise HTTP requests (`curl -v` and its output please)
-- Full log output (please enable debug mode)
-- Specific minimal steps to reproduce the issue from scratch
-- A working patch
-
-Please DO NOT use containers, VMs, cloud instances or services, or any other complex infrastructure in your steps. Always prefer `curl -v` instead of web browsers.
-
-We consider publicly-registered domain names to be public information. This necessary in order to maintain the integrity of certificate transparency, public DNS, and other public trust systems. Do not redact domain names from your reports. The actual content of your domain name affects Caddy's behavior, so we need the exact domain name(s) to reproduce with, or your report will be ignored.
-
-It will speed things up if you suggest a working patch, such as a code diff, and explain why and how it works. Reports that are not actionable, do not contain enough information, are too pushy/demanding, or are not able to convince us that it is a viable and practical attack on the web server itself may be deferred to a later time or possibly ignored, depending on available resources. Priority will be given to credible, responsible reports that are constructive, specific, and actionable. (We get a lot of invalid reports.) Thank you for understanding.
-
-When you are ready, please email Matt Holt (the author) directly: matt at dyanim dot com.
-
-Please don't encrypt the email body. It only makes the process more complicated.
-
-Please also understand that due to our nature as an open source project, we do not have a budget to award security bounties. We can only thank you.
-
-If your report is valid and a patch is released, we will not reveal your identity by default. If you wish to be credited, please give us the name to use and/or your GitHub username. If you don't provide this we can't credit you.
-
-Thanks for responsibly helping Caddy&mdash;and thousands of websites&mdash;be more secure!

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"

-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and

-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier

-
-## Install
-
-The simplest, cross-platform way to get started is to download Caddy from [GitHub Releases](https://github.com/caddyserver/caddy/releases) and place the executable file in your PATH.
-
-See [our online documentation](https://caddyserver.com/docs/install) for other install instructions.
-
-## Build from source
-
-Requirements:
-
-- [Go 1.20 or newer](https://golang.org/dl/)
-
-### For development
-
-_**Note:** These steps [will not embed proper version information](https://github.com/golang/go/issues/29228). For that, please follow the instructions in the next section._
-
-```bash
-$ git clone "https://github.com/caddyserver/caddy.git"
-$ cd caddy/cmd/caddy/
-$ go build
-```
-
-When you run Caddy, it may try to bind to low ports unless otherwise specified in your config. If your OS requires elevated privileges for this, you will need to give your new binary permission to do so. On Linux, this can be done easily with: `sudo setcap cap_net_bind_service=+ep ./caddy`
-
-If you prefer to use `go run` which only creates temporary binaries, you can still do this with the included `setcap.sh` like so:
-
-```bash
-$ go run -exec ./setcap.sh main.go
-```
-
-If you don't want to type your password for `setcap`, use `sudo visudo` to edit your sudoers file and allow your user account to run that command without a password, for example:
-
-```
-username ALL=(ALL:ALL) NOPASSWD: /usr/sbin/setcap
-```
-
-replacing `username` with your actual username. Please be careful and only do this if you know what you are doing! We are only qualified to document how to use Caddy, not Go tooling or your computer, and we are providing these instructions for convenience only; please learn how to use your own computer at your own risk and make any needful adjustments.
-
-### With version information and/or plugins
-
-Using [our builder tool, `xcaddy`](https://github.com/caddyserver/xcaddy)...
-
-```
-$ xcaddy build
-```
-
-...the following steps are automated:
-
-1. Create a new folder: `mkdir caddy`
-2. Change into it: `cd caddy`
-3. Copy [Caddy's main.go](https://github.com/caddyserver/caddy/blob/master/cmd/caddy/main.go) into the empty folder. Add imports for any custom plugins you want to add.
-4. Initialize a Go module: `go mod init caddy`
-5. (Optional) Pin Caddy version: `go get github.com/caddyserver/caddy/v2@version` replacing `version` with a git tag, commit, or branch name.
-6. (Optional) Add plugins by adding their import: `_ "import/path/here"`
-7. Compile: `go build`
-
-
-
-
-## Quick start
-
-The [Caddy website](https://caddyserver.com/docs/) has documentation that includes tutorials, quick-start guides, reference, and more.
-
-**We recommend that all users -- regardless of experience level -- do our [Getting Started](https://caddyserver.com/docs/getting-started) guide to become familiar with using Caddy.**
-
-If you've only got a minute, [the website has several quick-start tutorials](https://caddyserver.com/docs/quick-starts) to choose from! However, after finishing a quick-start tutorial, please read more documentation to understand how the software works. 🙂
-
-
-
-
-## Overview
-
-Caddy is most often used as an HTTPS server, but it is suitable for any long-running Go program. First and foremost, it is a platform to run Go applications. Caddy "apps" are just Go programs that are implemented as Caddy modules. Two apps -- `tls` and `http` -- ship standard with Caddy.
-
-Caddy apps instantly benefit from [automated documentation](https://caddyserver.com/docs/json/), graceful on-line [config changes via API](https://caddyserver.com/docs/api), and unification with other Caddy apps.
-
-Although [JSON](https://caddyserver.com/docs/json/) is Caddy's native config language, Caddy can accept input from [config adapters](https://caddyserver.com/docs/config-adapters) which can essentially convert any config format of your choice into JSON: Caddyfile, JSON 5, YAML, TOML, NGINX config, and more.
-
-The primary way to configure Caddy is through [its API](https://caddyserver.com/docs/api), but if you prefer config files, the [command-line interface](https://caddyserver.com/docs/command-line) supports those too.
-
-Caddy exposes an unprecedented level of control compared to any web server in existence. In Caddy, you are usually setting the actual values of the initialized types in memory that power everything from your HTTP handlers and TLS handshakes to your storage medium. Caddy is also ridiculously extensible, with a powerful plugin system that makes vast improvements over other web servers.
-
-To wield the power of this design, you need to know how the config document is structured. Please see [our documentation site](https://caddyserver.com/docs/) for details about [Caddy's config structure](https://caddyserver.com/docs/json/).
-
-Nearly all of Caddy's configuration is contained in a single config document, rather than being scattered across CLI flags and env variables and a configuration file as with other web servers. This makes managing your server config more straightforward and reduces hidden variables/factors.

-## Getting help
-
-- We advise companies using Caddy to secure a support contract through [Ardan Labs](https://www.ardanlabs.com/my/contact-us?dd=caddy) before help is needed.
-
-- A [sponsorship](https://github.com/sponsors/mholt) goes a long way! We can offer private help to sponsors. If Caddy is benefitting your company, please consider a sponsorship. This not only helps fund full-time work to ensure the longevity of the project, it provides your company the resources, support, and discounts you need; along with being a great look for your company to your customers and potential customers!
-
-- Individuals can exchange help for free on our community forum at https://caddy.community. Remember that people give help out of their spare time and good will. The best way to get help is to give it first!
-
-Please use our [issue tracker](https://github.com/caddyserver/caddy/issues) only for bug reports and feature requests, i.e. actionable development items (support questions will usually be referred to the forums).

-## About
-
-Matthew Holt began developing Caddy in 2014 while studying computer science at Brigham Young University. (The name "Caddy" was chosen because this software helps with the tedious, mundane tasks of serving the Web, and is also a single place for multiple things to be organized together.) It soon became the first web server to use HTTPS automatically and by default, and now has hundreds of contributors and has served trillions of HTTPS requests.
-
-**The name "Caddy" is trademarked.** The name of the software is "Caddy", not "Caddy Server" or "CaddyServer". Please call it "Caddy" or, if you wish to clarify, "the Caddy web server". Caddy is a registered trademark of Stack Holdings GmbH.

-// mapAddressToServerBlocks returns a map of listener address to list of server
-// blocks that will be served on that address. To do this, each server block is
-// expanded so that each one is considered individually, although keys of a
-// server block that share the same address stay grouped together so the config
-// isn't repeated unnecessarily. For example, this Caddyfile:
-//
-//	example.com {
-//		bind 127.0.0.1
-//	}
-//	www.example.com, example.net/path, localhost:9999 {
-//		bind 127.0.0.1 1.2.3.4
-//	}
-//
-// has two server blocks to start with. But expressed in this Caddyfile are
-// actually 4 listener addresses: 127.0.0.1:443, 1.2.3.4:443, 127.0.0.1:9999,
-// and 127.0.0.1:9999. This is because the bind directive is applied to each
-// key of its server block (specifying the host part), and each key may have
-// a different port. And we definitely need to be sure that a site which is
-// bound to be served on a specific interface is not served on others just
-// because that is more convenient: it would be a potential security risk
-// if the difference between interfaces means private vs. public.
-//
-// So what this function does for the example above is iterate each server
-// block, and for each server block, iterate its keys. For the first, it
-// finds one key (example.com) and determines its listener address
-// (127.0.0.1:443 - because of 'bind' and automatic HTTPS). It then adds
-// the listener address to the map value returned by this function, with
-// the first server block as one of its associations.
-//
-// It then iterates each key on the second server block and associates them
-// with one or more listener addresses. Indeed, each key in this block has
-// two listener addresses because of the 'bind' directive. Once we know
-// which addresses serve which keys, we can create a new server block for
-// each address containing the contents of the server block and only those
-// specific keys of the server block which use that address.
-//
-// It is possible and even likely that some keys in the returned map have
-// the exact same list of server blocks (i.e. they are identical). This
-// happens when multiple hosts are declared with a 'bind' directive and
-// the resulting listener addresses are not shared by any other server
-// block (or the other server blocks are exactly identical in their token
-// contents). This happens with our example above because 1.2.3.4:443
-// and 1.2.3.4:9999 are used exclusively with the second server block. This
-// repetition may be undesirable, so call consolidateAddrMappings() to map
-// multiple addresses to the same lists of server blocks (a many:many mapping).
