Feature request: have a request bypass the cache

[teodorescuserban]

I am using caddy and souin as caddy plugin. I have a request from an app owner to be able to make request directly, skipping the cache if the request includes a custom header. I can do it really simple by altering the matcher (see my solution below), but this will bypass the cache module altogether. Ideally, I would like to have the cache module do its own bypass and send the headers (something like cache-status: cache; fwd=uri-miss; key=xxx; detail=BYPASS-REQUESTED).

Not sure how easy is this to implement across all integrations, but putting this out as an idea.

# caddy example
...
map {http.request.uri} {wants_cache} {
	default 0
	"~^/a1" 1
	"~^/a2" 1
}
...
map {http.request.header.some-custom-header} {bypass_cache} {
	default 1
	"" 0
}
...
@needs_cache expression `{wants_cache} == "1" && {bypass_cache} == "0"`
...
cache @needs_cache
...

@teodorescuserban that's currently not possible and I don't plan to implement this requested feature because I don't see the benefits.
