I'm not sure if this is a bug in HAProxy, or if upgrading HAProxy to 1.4 has
uncovered a bug in my application.
I am developing a web app that uses long polling. I'm proxying its requests
through haproxy. I've noticed that when reload the page in the browser
(which presumably severs the connection that the javascript is holding open
to the server through haproxy), I get an http status 502 error logged by
haproxy. It looks something like this:
Mar 23 12:43:45 localhost haproxy-1.5v4[5969]:
96.246.63.146:61899[23/Mar/2011:12:43:25.276] http_proxy
backend1/backendserver1 6/0/0/-1/20014
502 204 - - SH-- 0/0/0/0/0 0/0
{proxy.myserver|65|http://proxy.myserver|Mozilla/5.0
(Macinto} {|} "POST / HTTP/1.1"
This happens in Haproxy version 1.5-dev3 and 1.5-dev4, but it does not
happen in haproxy version 1.4.13. Is there some additional investigation I
can do to determine if it's a bug in 1.5x or just something that my web app
shouldn't have been doing anyway that is now (correctly) being logged as an
error by 1.5x?
thanks,
Cory
