Re: SSL Pass through and sticky session

Yea that is the problem. Right now SSL is terminated at the application level on each server. There is no way to inspect the cookie even if the server sets one. Sticky session in TCP mode can be done by source IP (that is why I have balance source). But that creates the other problem as I mentioned. Folks coming from behind NAT will hit the same server and not get load balanced. Because HAProxy will think they are all the same. I was trying to find out if there is something else that could be done. From my own logical reasoning, no. :) but I have been wrong before so I was hoping someone had similar issue.

Thanks

But then users behind a firewall/NAT will not get load balanced correctly. Instead, they all end up on same server. That is my main problem.
