Also, if you can reproduce that on unitary tests, could you please run
"strace -o /tmp/haproxy.trace -p $(pidof haproxy)" and send me the file
/tmp/haproxy.trace ?
I will try to reproduce this today and send you the file.
well, please try the patches from the other mail first, as I
managed to reproduce the issue here and to fix it. If you feel
uneasy with applying patches, you can use the latest snapshot
here instead :

I applied the 2 patches, 0013 - 0014, if I am correct, no success. But I
noticed some co-workers have no problem at all. I think it is due to the
cookie, that contains illegal stuff.
I'll try to put a webservice on the local box of haproxy to see the
errors, because now i can't see where in the header parsing it goes
wrong. I base myself on the PH-- and the -1 you noticed,
that means that the header parsing contained errors. Is there a way
around this? I'll diff the cookies to check any differences. If you
still want the strace i can provide you this. The tcpdump is a
little more difficult since everything has to happen live, alot of info
flows through. I cannot filter on client ip since haproxy hides it. But
i saw resets on the backend box, when i performend the logout.
# /var/log/apache2# tcpdump -i eth0.2 -l "tcp dst port 80 and
((tcp[tcpflags] & tcp-rst) = tcp-rst)"
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0.2, link-type EN10MB (Ethernet), capture size 96 bytes
