-- Use httpserver.Path to compare base paths to know if your handler should handle the request
+- Use `httpserver.Path` to compare base paths to know whether your handler should handle the request
 - Don't touch the file system using a path from the request directly. Instead:
-    - To open a file, use http.Dir
-    - For anything else, use httpserver.SafePath to get a sanitized path
-- If you need to wrap or record the response, wrap your own ResponseWriter type with httpserver.ResponseWriterWrapper so it is guaranteed to implement some crucial interfaces.

+    - To open a file, use `http.Dir` (standard lib)
+    - For anything else, use `httpserver.SafePath` to get a sanitized path
+- If you need to wrap or record the response, wrap your own `ResponseWriter` type with `httpserver.ResponseWriterWrapper` so it is guaranteed to implement some crucial interfaces.
+- The `http.Request.URL` (especially its `.Path` value) may be changed by other "rewriting" middlewares. You can always access the original incoming URL via context: `req.Context().Value(httpserver.OriginalURLCtxKey).(url.URL)`
