Getting error 502 Bad Gateway

Hi Everyone,

We are having some issues with our haproxy servers, when I go to my web servers and restart them, I take them out of haproxy before restarting my apache servers, but afterwards some people are getting the "502 Bad Gateway The server returned an invalid or incomplete response" error. It doesn't happen every time, I could be jumping around in the web site and then have the "502 Bad Gateway" thrown to us.

I have gone into my haproxy.conf and set "cookie SERVERID rewrite" originally we had it "cookie SERVERID insert indirect nocache" and I had "capture cookie ASPSESSION len 32" which I have now removed.

Even after making these changes, we are still getting the errors. Can someone suggest a fix or a way around this issue? I am putting in the config below.

Also, I upgraded to 1.3.15.6 from 1.3.15.5 and we are still getting the 502 errors. I can go directly to the server and get the web page with no problem.

Thanks to everyone for any help.

Joe
