43b56d621b Allow duplicate Server headers when proxying response
See discussion on commit c9b022b5e0

If we overwrite the Server header, it becomes difficult/impossible to
know from the client whether the request was proxied through Caddy.

d5371aff22 httpserver/all: Clean up and standardize request URL handling (#1633)
* httpserver/all: Clean up and standardize request URL handling

The HTTP server now always creates a context value on the request which
is a copy of the request's URL struct. It should not be modified by
middlewares, but it is safe to get the value out of the request and make
changes to it locally-scoped. Thus, the value in the context always
stores the original request URL information as it was received. Any
rewrites that happen will be to the request's URL field directly.

The HTTP server no longer cleans /sanitizes the request URL. It made too
many strong assumptions and ended up making a lot of middleware more
complicated, including upstream proxying (and fastcgi). To alleviate
this complexity, we no longer change the request URL. Middlewares are
responsible to access the disk safely by using http.Dir or, if not
actually opening files, they can use httpserver.SafePath().

I'm hoping this will address issues with #1624, #1584, #1582, and others.

* staticfiles: Fix test on Windows

@abiosoft: I still can't figure out exactly what this is for. 😅

* Use (potentially) changed URL for browse redirects, as before

* Use filepath.ToSlash, clean up a couple proxy test cases

* Oops, fix variable name

5a41e8bc1a proxy: Fixed #1484, websockets with h2 disabled (#1488)
* Fixed #1484

Fixed a nil pointer runtime error in newConnHijackerTransport,
where the access to the TLSClientConfig did not check for nil values.

* Minor improvement to UseInsecureTransport

This prevents overwriting a possibly preexisting TLSClientConfig,
even though only a single field should be changed.

9f9ad21aaa Fixed #1292: Failure to proxy WebSockets over HTTPS
This issue was caused by connHijackerTransport trying to record HTTP
response headers by "hijacking" the Read() method of the plain net.Conn.
This does not simply work over TLS though since this will record the TLS
handshake and encrypted data instead of the actual content.
This commit fixes the problem by providing an alternative transport.DialTLS
which correctly hijacks the overlying tls.Conn instead.

a3aa414ff3 Fixed HTTP/2 support for the proxy middleware (#1300)
* Fixed HTTP/2 support for the proxy middleware

http.Transport instances whose TLSClientConfig, Dial, or DialTLS field
is non-nil will be configured without HTTP/2 support by default.

This commit adds the proper calls to http2.ConfigureTransport()
everywhere a http.Transport is created and thus fixes HTTP/2 in the
proxy middleware whenever insecure_skip_verify or keepalive is provided.

* Added HTTP/2 support check to TestReverseProxyInsecureSkipVerify

3dc98c8ce3 Keep quic protocol headers only between one hop
Removing quic protocol headers from being persisted during proxy requests.
Not removing them could lead to the client attempting to connect to the wrong port.
This makes the quic headers consistent with other protocol headers.
