I’m trying to use Haproxy 1.8 on debian 10 distrib (buster) with an apache backend.
When I try to Access a page in which we set a cookie, I’m encountering a 502 Bad Gateway.
Looking at the log, I can see that it’s a PH-- error so answer of server seems to be the cause but I haven’t any other clue.
Activating debug mode didn’t help me.
I’ve tried in tcp mode it works but I can’t use or because my routing is based on http header.
Tried with apache with proxy mode activated and it works fine.
I’ve also tried to accept Bad request ans réponse in option also to set “no option checkcache” even if “option checkcache IS not set anywhere” but it also didn’t work
Any ideas of the issue?
