Automatically use reverse proxy headers when present

[faermanj]

Description

When generating redirects (like Response.seeOther()), behind a reverse proxy, UriInfo.getBaseURI() will generate incorrect URLs and fail unless proxy support is configured with quarkus.http.proxy.proxy-address-forwarding=true and quarkus.http.proxy.enable-forwarded-host=true.
So, unless developers know this beforehand, applications will break when being moved from "unproxied" to "proxied", such as moving "dev" to "prod", with only a with a malformed url exception.
It would be more reliable to always use proxy headers when present, or unless configured otherwise.

This is indeed very interesting!

Mind attaching a sample that we can use to test potential solutions against?
