is this some sort of haproxy bug?

view story

http://serverfault.com – I go from http://sniffyourkid.com and then change the url to http://sniffyourkid.com/blog and it fails to go to apache and instead goes to my other webserver where sniffyourkid.com is. THIS IS INTERMITTENT and sometimes happens more often from www.sniffyourkid.com/ to www.sniffyourkid.com/blog. If I refresh a few times it finally goes to apache. It is soooo weird. In wireshark, I see from the trace, it is incorrectly hitting the wrong webserver AND I see weird TCP out of order packets(not sure if it is important) # this config needs haproxy-1.1.28 or haproxy-1.2.1 global log 127.0 (HowTos)
