Issue:
Infinite loop on goroutine with http.ResponseController changes
Not sure what happened - I was running `master` on this server for a while, last updated to commit e041962b66c45db8baab95b71a65f4c164736684 I believe. I got notified for the Caddy 2.7 release, I re-built it, and now ~~HTTP/3 fails on this specific server by crashing on the first request it gets~~ it seems to be crashing when `encode` is enabled and the client requests compression.

Caddy version is `v2.7.0 h1:ZrAwnBzZ/FBoNw+WBlF2HER8oEs/O7c20ku6nbWFqco=`, running on Fedora 38.
Built using Go v1.20.7. (Past working build was on v1.20.6)

```
systemd[1]: Started caddy.service - Caddy.
caddy[69585]: runtime: goroutine stack exceeds 1000000000-byte limit
caddy[69585]: runtime: sp=0xc0209e0398 stack=[0xc0209e0000, 0xc0409e0000]
caddy[69585]: fatal error: stack overflow
systemd[1]: caddy.service: Main process exited, code=exited, status=2/INVALIDARGUMENT

```

The info below is now invalid, as it seems to be unrelated.

```
(Not sure what's up with my curl there - it eats all the RAM it can until the OOM killer terminates it. On Firefox it stays infinitely loading.)

The config isn't something big, either:
```
xxx {
	import common

	header {
		X-Robots-Tag "none"
		-X-Powered-By
		-Server
	}

	header /api/collect {
		Access-Control-Max-Age "86400"
	}

	reverse_proxy 127.0.0.1:3000
}
```

`common` is merely this:
```
(common) {
	encode {
		zstd
		gzip
	}
}
```

HTTP/2 seems to be experiencing no crashes, only HTTP/3.


Discussion / hints:
`QUIC_GO_ENABLE_GSO=true` is unrelated - crashes without it. Will keep trying to see if I can pinpoint when was the issue introduced/what triggers it.
Also noticing some issues now.

Very strange -- was not having issues with testing earlier even today.
Pinging @marten-seemann just in case
Can you post the stack trace please?
@marten-seemann It doesn't throw a trace while crashing. I can get it for you; just not sure how at the moment.

Also, I checked out commit e198c605bd68f4b3630e5fa1ae9f7ca5cac1a7d9 and the server's back functional. Wondering if cd486c25d168caf58f4b6fe5d3252df9432901ec could be the cause? (@mholt / @francislavoie)

Keep in mind that I'm not enabling `enable_full_duplex` on my config.
Can you try without `encode` and without `header` as well to narrow it down?

Sorry about this 😩 I guess we were a bit hasty with that commit.
Seems like HTTP/3 isn't related in here, and cd486c25d168caf58f4b6fe5d3252df9432901ec is indeed the culprit. Must have been a coincidence in my case...

@francislavoie Disabling `encode` fixed it. Works with or without `header`, just not `encode`.

```
I'm trying to reproduce but I'm having trouble with HTTP/3 locally :grimacing: why do browsers make it so hard to force HTTP/3 :cry: and my usual build of curl https://github.com/yurymuski/curl-http3 doesn't support `--compressed`. Setting up a VM now to test it instead.
As mentioned, doesn't seem to be related to HTTP/3 - it's crashing for me on HTTP/2 too, my belief of it being related to HTTP/3 was likely something else doing a request to the server at the same time I was doing one too. It's just merely related to compression.
Oh, well I can't get it to crash with HTTP/2 either. :thinking: 
 I have encountered the same issue. Here stacktrace:
