2022-12-05reverseproxy: Improve hostByHashing distribution (#5229)Alban Lecocq
* 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

2022-09-27reverseproxy: fix upstream scheme handling in command (#5088)lemmi
e338648fed3263200dfd6abc9f8100c6f1c0eb67 introduced multiple upstream addresses. A comment notes that mixing schemes isn't supported and therefore the first valid scheme is supposed to be used. Fixes setting the first scheme. fixes #5087

2022-09-16core: Variadic Context.Logger(); soft deprecationMatthew Holt
Ideally I'd just remove the parameter to caddy.Context.Logger(), but this would break most Caddy plugins. Instead, I'm making it variadic and marking it as partially deprecated. In the future, I might completely remove the parameter once most plugins have updated.

2022-06-28forwardauth: Fix case when `copy_headers` is omitted (#4856)Francis Lavoie
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.

Closes #4823
2022-06-02reverseproxy: api: Remove misleading 'healthy' valueMatthew Holt
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.
