caddy ignores `no-cache` and serves cached response

[subnix]

If a response contains ETag and Cache-Control with no-cache, caddy ignores no-cache and serves cached response with default ttl without validation.

Reproduction steps:

 {
     log
     cache
 }

 http://localhost:80 {
     log
     cache
     reverse_proxy http://localhost:81
 }

 http://localhost:81 {
     log
     header ETag "\"3e25960a79dbc69b674cd4ec67a72c62\""
     header Cache-Control "no-cache"
     respond "Hello world"
 }

$ curl -i localhost:80
HTTP/1.1 200 OK
Cache-Control: no-cache
Cache-Status: Souin; fwd=uri-miss; stored; key=GET-http-localhost-/
....

$ curl -i localhost:80
HTTP/1.1 200 OK
Age: 11
Cache-Control: no-cache
Cache-Status: Souin; hit; ttl=109; key=GET-http-localhost-/; detail=DEFAULT
...

caddy version
v2.10.2 h1:g/gTYjGMD0dec+UgMw8SnfmJ3I9+M2TdvoRL/Ovu6U8=

Hey @subnix can you try using this hash 2e1f6692f8473b66b0ef51e132d7b95e9a0c0684 please?

@darkweak Unfortunately, it still serves a cached response. I've also tried this config, but to no avail.

{
    log
    cache {
        stale 3600s
    }
}

http://:8080 {
    log
    cache
    reverse_proxy http://localhost:82
}

http://localhost:82 {
    log
    header Cache-Control "no-cache"
    file_server {
        root /data/caddy/
        index instance.uuid
    }
}
