[Bug 50807] mod_proxy fails to send FIN response when a FIN is received from a backend


https://bz.apache.org/bugzilla/show_bug.cgi?id=50807

--- Comment #13 from Yann Ylavic <ylavic.dev@xxxxxxxxx> ---
The main difference between 1.3 and 2.2+ (possibly 2.0 too) is that backend
connections are managed/reused independently from the clients' ones.

In 1.3 the backends and clients connections were closed together (at worst when
client's KeepAlive expires), this is not the case anymore.

Pros: big performance win (think of TLS and/or TCP-3WAY handshakes saved, which
quite matters on heavy load).
Cons: ttl fine tuning (according to / lower than the backend's
KeepAliveTimeout), both for keeping CLOSE_WAIT sockets low AND avoid reuse race
conditions.
