I've also hit this issue in May (https://www.mail-archive.com/[email protected]/msg37170.html), and as many continue to upgrade to newer HAProxy versions, they might hit that as well. Personally I've opted into using variables set from request / response rules, and then logging those in a custom log format. However the major issue, if I remember correctly, isn't that the format has changed between HAProxy 2.0 and 2.1, but that in 2.1 the same `%HP` produces different outputs based on the used protocol, which will complicate log handling... Perhaps a backward incompatible fix would be to always include the protocol and `Host` header (or the IP if one is missing) in case of HTTP/1.0 and HTTP/1.1, and thus have `%HP` always contain an URL. > I believe this is expected; this behaviour has changed since v2.1 though. It might be so, but the changelog for 2.1 says nothing about this change. Ciprian.
