Unfortunately I the "show errors" returned empty, so I guess it was something else. The good news is that I gave haproxy 1.4.2 a try today and the 502/PR error with PUT/TE:chunked requests have now vanished. So thanks for solving this. I'm not sure which one of the bugs I was hitting but it does not really matter since it now seems to be fixed. So now when I got a working haproxy 1.4, I continued to try out the "option http-server-close" but I hit a problem with our stunnel (patched with stunnel-4.22-xforwarded-for.diff) instances. It does not support keep-alive, so only the first HTTP request in a keepalive-session gets the X-Forwarded-For header added (insert Homer "doh!" here :). When giving it some thought, I guess this is the expected behaviour for what stunnel actually is supposed to do. So, for now I'll stick with "option httpclose" for a while longer... Keep up the good work! Best regards Erik -- Erik Gulliksson, erik.gulliks...@diino.net System Administrator, Diino AB http://www.diino.com
