When only a single request has the least amount of requests, there's no need to compute a random number, because the modulo of 1 will always be 0 anyways.

* If upstreams are all using same host but with different ports
ie:
foobar:4001
foobar:4002
foobar:4003
...
Because fnv-1a has not a good enough avalanche effect
Then the hostByHashing result is not well balanced over
all upstreams
As last byte FNV input tend to affect few bits, the idea is to change
the concatenation order between the key and the upstream strings
So the upstream last byte have more impact on hash diffusion

This is something that has bothered me for a while, so I figured I'd do something about it now since I'm playing in the logging code lately.
The `console` encoder doesn't actually match the defaults that zap's default logger uses. This makes it match better with the rest of the logs when using the `console` encoder alongside somekind of filter, which requires you to configure an encoder to wrap.
PR #4066 added a dark color scheme to the file_server browse template.
PR #4356 later set the links for the `:visited` pseudo-class, but did
not set anything for the dark mode, resulting in poor contrast. I
selected some new colors by feel.
This commit also adds an `a:visited:hover` for both, to go along with
the normal blue hover colors.
It was not accurate. Placeholders could be used in outputs that are
defined in the same mapping as long as that placeholder does not do the
same.
A more general solution would be to detect it at run-time in the
replacer directly, but that's a bit tedious
and will require allocations I think.
A better implementation of this check could still be done, but I don't
know if it would always be accurate. Could be a "best-effort" thing?
But I've also never heard of an actual case where someone configured
infinite recursion...
* core: Refactor, improve listener logic
Deprecate:
- caddy.Listen
- caddy.ListenTimeout
- caddy.ListenPacket
Prefer caddy.NetworkAddress.Listen() instead.
Change:
- caddy.ListenQUIC (hopefully to remove later)
- caddy.ListenerFunc signature (add context and ListenConfig)
- Don't emit Alt-Svc header advertising h3 over HTTP/3
- Use quic.ListenEarly instead of quic.ListenEarlyAddr; this gives us
more flexibility (e.g. possibility of HTTP/3 over UDS) but also
introduces a new issue:

We also wait for them to start up so we can be fairly confident the

accepting new connections.

Until now, the vars matcher has unintentionally lacked parity with the
map directive: the destination placeholders of the map directive would
be expressed as placeholders, i.e. {foo}. But the vars matcher would
not use { }: vars foo value
This looked weird, and was confusing, since it implied that the key
could be dynamic, which doesn't seem helpful here.
I think this is a proper bug fix, since we're not used to accessing
placeholders literally without { } in the Caddyfile.
* core: Plugins can register listener networks
This can be useful for custom listeners.
This feature/API is experimental and may change!
* caddyhttp: Expose server listeners
This allows users to, for example, get upstreams from multiple SRV
endpoints in order (such as primary and secondary clusters).
Also, gofmt went to town on the comments, sigh
Errors returned from the DecisionFunc (whether to get a cert on-demand)
are used as a signal whether to allow a cert or not; *any* error
will forbid cert issuance.
We bubble up the error all the way to the caller, but that caller is the
Go standard library which might gobble it up.
Now we explicitly log connection errors so sysadmins can
ensure their ask endpoints are working.
Thanks to our sponsor AppCove for reporting this!
* fileserver: Support virtual file systems (close#3720)
This change replaces the hard-coded use of os.Open() and os.Stat() with
the use of the new (Go 1.16) io/fs APIs, enabling virtual file systems.
It introduces a new module namespace, caddy.fs, for such file systems.
Also improve documentation for the file server. I realized it was one of
the first modules written for Caddy 2, and the docs hadn't really been
updated since!
* Virtualize FS for file matcher; minor tweaks
* Fix tests and rename dirFS -> osFS
(Since we do not use a root directory, it is dynamic.)
Hahaha this is the ultimate "I have no idea what I'm doing" commit but it

... probably broke something, should be tested more.
It is nice that the protobuf dependency becomes indirect now.
* reverseproxy: Implement retry count, alternative to try_duration

* Fix lint
See https://caddy.community/t/using-forward-auth-and-writing-my-own-authenticator-in-php/16410, apparently it didn't work when `copy_headers` wasn't used. This is because we were skipping adding a handler to the routes in the "good response handler", but this causes the logic in `reverseproxy.go` to ignore the response handler since it's empty. Instead, we can just always put in the `header` handler, even with an empty `Set` operation, it's just a no-op, but it fixes that condition in the proxy code.

In v2.5.0, upstream health was fixed such that whether an upstream is
considered healthy or not is mostly up to each individual handler's
config. Since "healthy" is an opinion, it is not a global value.
I unintentionally left in the "healthy" field in the API endpoint for
checking upstreams, and it is now misleading (see #4792).
However, num_requests and fails remains, so health can be determined by
the API client, rather than having it be opaquely (and unhelpfully)
determined for the client.
If we do restore this value later on, it'd need to be replicated once
per reverse_proxy handler according to their individual configs.
* reverseproxy: Improve hashing LB policies with HRW
Previously, if a list of upstreams changed, hash-based LB policies
would be greatly affected because the hash relied on the position of
upstreams in the pool. Highest Random Weight or "rendezvous" hashing
is apparently robust to pool changes. It runs in O(n) instead of
O(log n), but n is very small usually.

* reverseproxy: New `copy_response` handler for `handle_response` routes
Followup to #4298 and #4388.
This adds a new `copy_response` handler which may only be used in `reverse_proxy`'s `handle_response` routes, which can be used to actually copy the proxy response downstream.
Previously, if `handle_response` was used (with routes, not the status code mode), it was impossible to use the upstream's response body at all, because we would always close the body, expecting the routes to write a new body from scratch.
To implement this, I had to refactor `h.reverseProxy()` to move all the code that came after the `HandleResponse` loop into a new function. This new function `h.finalizeResponse()` takes care of preparing the response by removing extra headers, dealing with trailers, then copying the headers and body downstream.
Since basically what we want `copy_response` to do is invoke `h.finalizeResponse()` at a configurable point in time, we need to pass down the proxy handler, the response, and some other state via a new `req.WithContext(ctx)`. Wrapping a new context is pretty much the only way we have to jump a few layers in the HTTP middleware chain and let a handler pick up this information. Feels a bit dirty, but it works.
Also fixed a bug with the `http.reverse_proxy.upstream.duration` placeholder, it always had the same duration as `http.reverse_proxy.upstream.latency`, but the former was meant to be the time taken for the roundtrip _plus_ copying/writing the response.
* Delete the "Content-Length" header if we aren't copying
Fixes a bug where the Content-Length will mismatch the actual bytes written if we skipped copying the response, so we get a message like this when using curl:
```
curl: (18) transfer closed with 18 bytes remaining to read
```
To replicate:
```
{
admin off
debug
}
:8881 {
reverse_proxy 127.0.0.1:8882 {
@200 status 200
handle_response @200 {
header Foo bar
}
}
}
:8882 {
header Content-Type application/json
respond `{"hello": "world"}` 200
}
```

* Add a override_domain option to allow DNS chanllenge delegation
CNAME can be used to delegate answering the chanllenge to another DNS

to allow the user explicitly specify the domain to delegate, instead of
following the CNAME chain.

The TestFileListing test in tplcontext_test has one test that verifies
if directory traversal is not happening. The context root is set to
'/tmp' and then it tries to open '../../../../../etc', which gets
normalized to '/tmp/etc'.
The test then expects an error to be returned, assuming that '/tmp/etc'
does not exist on the system. When it does exist, it results in a test
failure:
```
--- FAIL: TestFileListing (0.00s)
tplcontext_test.go:422: Test 4: Expected error but had none
FAIL
FAIL
github.com/caddyserver/caddy/v2/modules/caddyhttp/templates 0.042s
```
Instead of using '/tmp' as root, use a dedicated directory created with
`os.MkdirTemp()` instead. That way, we know that the directory is empty.

This is a followup to #4407, in response to a report on the forums: https://caddy.community/t/php-fastcgi-phishing-redirection/14542
Turns out that doing `TrimRight` to remove trailing dots, _before_ cleaning the path, will cause double-dots at the end of the path to not be cleaned away as they should. We should instead remove the dots _after_ cleaning.

* reverseproxy: Adjust defaults, document defaults
Related to some of the issues in https://github.com/caddyserver/caddy/issues/4245, a complaint about the proxy transport defaults not being properly documented in https://caddy.community/t/default-values-for-directives/14254/6.
- Dug into the stdlib to find the actual defaults for some of the timeouts and buffer limits, documenting them in godoc so the JSON docs get them next release.
- Moved the keep-alive and dial-timeout defaults from `reverseproxy.go` to `httptransport.go`. It doesn't make sense to set defaults in the proxy, because then any time the transport is configured with non-defaults, the keep-alive and dial-timeout defaults are lost!
- Sped up the dial timeout from 10s to 3s, in practice it rarely makes sense to wait a whole 10s for dialing. A shorter timeout helps a lot with the load balancer retries, so using something lower helps with user experience.
* reverseproxy: Make keepalive interval configurable via Caddyfile
* fastcgi: DialTimeout default for fastcgi transport too
Fixes#4428
It's best to still log handler errors at debug level so that they're hidden by default, but still accessible if additional details are necessary.
This makes it easier for users to find the default browse template if they
want to create a custom template based on that. It also makes it easier to
view the template with proper syntax highlighting.

Related to (closed) Issue #2094 on template inheritance. This PR adds a new function called "import" which works like "include", except it only takes one argument and passes it to the referenced file to be used as "." in that file.

* encode: ignore flushing until after first write (fix#4314)
The first write will determine if encoding has to be done and will add an Content-Encoding. Until then Flushing has to be delayed so the Content-Encoding header can be added before headers and status code is written. (A passthrough flush would write header and status code)
* Update modules/caddyhttp/encode/encode.go

From reading through the code, I think this code path is now obsoleted by the changes made in https://github.com/caddyserver/caddy/pull/4266.
Basically, `h.flushInterval()` will set the flush interval to `-1` if we're in a bi-directional stream, and the recent PR ensured that `h.copyResponse()` properly flushes headers immediately when the flush interval is non-zero. So now there should be no need to call Flush before calling `h.copyResponse()`.
