core: Fix dyslexic/backward handling of 403/404 errors

If we do not use a pointer here, the startup function that opens the log file stores the log file in a copy of the handler, not the same instance of the handler, causing panics during requests, which is bad, especially when the response is gzipped: the next recover() is beyond the gzip handler, so the browser downloads a gz file instead.

-### Contributing code
-
-You can have a huge impact on the project by helping with its code. To contribute code to Caddy, 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/-/search).
-
-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.
-
-- **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.** Tests are essential! 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 or 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`.
-
-- **Own 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.
-
-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. 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, get it with `go get github.com/caddyserver/caddy/v2`.
-
-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 stop bugs in their tracks!** 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.
-
-Please follow the issue 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. The burden is on you 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 undesired or surprising behavior which violates documentation or the spec.
-
-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.
-	- Otherwise, the burden is on the reporter to test possible solutions. This is discouraged 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 (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.
-
-
-### 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.
-
-
-
-## 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
-
-- 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
-
-The Caddy project would like to make sure that it stays on top of all practically-exploitable vulnerabilities.
-
-Some security problems are more the result of interplay between different components of the Web, rather than a vulnerability in the web server itself. Please report only 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 or BGP hijacks a vulnerability in the Caddy web server).
-
-Please note that 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.

-
-## Reporting a Vulnerability
-
-Please email Matt Holt (the author) directly: matt [at] lightcodelabs [dot com].
-
-We'll need enough information to verify the bug and make a patch. 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, resources permitting. Priority will be given to credible, responsible reports that are constructive, specific, and actionable. Thank you for understanding.
-
-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!

+## Contributing to Caddy
+
+This project gladly accepts contributions. Interested users are encouraged to get involved by [opening issues](https://github.com/mholt/caddy/issues) with their ideas, questions, and bug reports. Bug reports should contain clear instructions to reproduce the problem and state expected behavior.
+
+For small tweaks and bug fixes, feel free to submit [pull requests](https://github.com/mholt/caddy/pulls) at any time. For new features or to change existing behavior, please open an issue first to discuss it and claim it. This prevents overlapping efforts and also keeps the project in-line with its goals.
+
+If you've found a vulnerability that is serious, please email me: Matthew dot Holt at Gmail. If it's not a big deal, a pull request will probably be faster.
+
+Thanks for your help!

+
+Caddy is a lightweight, general-purpose web server for Windows, Mac, Linux, BSD, and [Android](https://github.com/mholt/caddy/wiki/Running-Caddy-on-Android). It is a capable alternative to other popular web servers.
+
+The most notable features are HTTP/2, Virtual Hosts, TLS + SNI, and easy configuration with a [Caddyfile](https://caddyserver.com/docs/caddyfile). Usually, you have one Caddyfile per site. Most directives for the Caddyfile invoke a layer of middleware which can be [used in your own Go programs](https://github.com/mholt/caddy/wiki/Using-Caddy-Middleware-in-Your-Own-Programs).

-## [Features](https://caddyserver.com/v2)
 
-- **Easy configuration** with the [Caddyfile](https://caddyserver.com/docs/caddyfile)
-- **Powerful configuration** with its [native JSON config](https://caddyserver.com/docs/json/)
-- **Dynamic configuration** with the [JSON API](https://caddyserver.com/docs/api)
-- [**Config adapters**](https://caddyserver.com/docs/config-adapters) if you don't like JSON
-- **Automatic HTTPS** by default
-	- [ZeroSSL](https://zerossl.com) and [Let's Encrypt](https://letsencrypt.org) for public names
-	- Fully-managed local CA for internal names & IPs
-	- Can coordinate with other Caddy instances in a cluster
-	- Multi-issuer fallback
-- **Stays up when other servers go down** due to TLS/OCSP/certificate-related issues
-- **Production-ready** after serving trillions of requests and managing millions of TLS certificates
-- **Scales to tens of thousands of sites** ... and probably more
-- **HTTP/1.1, HTTP/2, and experimental HTTP/3** support
-- **Highly extensible** [modular architecture](https://caddyserver.com/docs/architecture) lets Caddy do anything without bloat
-- **Runs anywhere** with **no external dependencies** (not even libc)
-- Written in Go, a language with higher **memory safety guarantees** than other servers
-- Actually **fun to use**
-- So, so much more to [discover](https://caddyserver.com/v2)
 
-## Install
+## Getting Caddy
 
-The simplest, cross-platform way is to download from [GitHub Releases](https://github.com/caddyserver/caddy/releases) and place the executable file in your PATH.
+Caddy binaries have no dependencies and are available for nearly every platform.
 
-For other install options, see https://caddyserver.com/docs/download.
+[Latest release](https://github.com/mholt/caddy/releases/latest)
 
-## Build from source
 
-Requirements:
+## Running from Source
 
-- [Go 1.14 or newer](https://golang.org/dl/)
+1. `$ go get github.com/mholt/caddy`
+2. `cd` into your website's directory
+3. Run `caddy` (assumes `$GOPATH/bin` is in your `$PATH`)
 
-### 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._
+If you're tinkering, you can also use `go run main.go`.
 
-```bash
-$ git clone "https://github.com/caddyserver/caddy.git"
-$ cd caddy/cmd/caddy/
-$ go build
-```
+By default, Caddy serves the current directory at [localhost:2015](http://localhost:2015). You can place a Caddyfile to configure Caddy for serving your site.
 
-When you run Caddy, it may try to bind to low ports unless otherwise specified in your config. If your OS requires elevated privileges, 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`
+Caddy accepts some flags from the command line. Run `caddy -h` to view the help for flags.
 
-If you prefer to use `go run` which creates temporary binaries, you can still do this. Make an executable file called `setcap.sh` (or whatever you want) with these contents:
 
-```bash
-#!/bin/sh
-sudo setcap cap_net_bind_service=+ep "$1"
-"$@"
-```
+#### 3rd-party libraries
 
-then you can use `go run` like so:
+Although Caddy's binaries are completely static, Caddy relies on some excellent libraries that really make the project possible.
 
-```bash
-$ go run -exec ./setcap.sh main.go
-```
+- [bradfitz/http2](https://github.com/bradfitz/http2) for HTTP/2 support
+- [russross/blackfriday](https://github.com/russross/blackfriday) for Markdown rendering
+- [dustin/go-humanize](https://github.com/dustin/go-humanize) for pleasant times and sizes
+- [flynn/go-shlex](https://github.com/flynn/go-shlex) to parse shell commands properly
 
-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:
+This list may not be comprehensive, but [godoc.org](https://godoc.org/github.com/mholt/caddy) will list all packages that any given package imports.
+
+## Quick Start
+
+The website has [full documentation](https://caddyserver.com/docs) but this will get you started in about 30 seconds:
+
+Place a file named "Caddyfile" with your site. Paste this into it and save:
 
 ```
-username ALL=(ALL:ALL) NOPASSWD: /usr/sbin/setcap
+localhost
+
+gzip
+browse
+ext .html
+websocket /echo cat
+log ../access.log
+header /api Access-Control-Allow-Origin *
 ```
 
-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.
+Run `caddy` from that directory, and it will automatically use that Caddyfile to configure itself.
 
-### With version information and/or plugins
+That simple file enables compression, allows directory browsing (for folders without an index file), serves clean URLs, hosts an echo server for WebSocket connections at /echo, logs accesses to access.log, and adds the coveted `Access-Control-Allow-Origin: *` header for all responses from some API.
 
-Using [our builder tool, `xcaddy`](https://github.com/caddyserver/xcaddy)...
+Wow! Caddy can do a lot with just a few lines.
+
+#### Defining multiple sites
+
+You can run multiple sites from the same Caddyfile, too:
 
 ```
-$ xcaddy build
+http://mysite.com,
+http://www.mysite.com {
+	redir https://mysite.com
+}
+
+https://mysite.com {
+	tls mysite.crt mysite.key
+	# ...
+}
 ```
 
-...the following steps are automated:
+Note that the secure host will automatically be served with HTTP/2 if the client supports it.
 
-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 or commit.
-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. 🙂
+## Contributing
+
+This project gladly accepts contributions. Interested users are encouraged to get involved by opening issues with their ideas, questions, and bug reports. Bug reports should contain clear instructions to reproduce the problem and state expected behavior.
+
+For small tweaks and bug fixes, feel free to submit pull requests at any time. For new features or to change existing behavior, please open an issue first to discuss it and claim it. This prevents overlapping efforts and also keeps the project in-line with its goals.
+
+Thanks for making Caddy -- and the Web -- better!
 
 
 
 
-## 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.
+## About the project
 
-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.
+Caddy was born out of the need for a "batteries-included" web server that runs anywhere and doesn't have to take its configuration with it. Caddy took inspiration from nginx, lighttpd, Websocketd, and Vagrant, and provides a pleasant mixture of features from each of them.

-// 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).
