Ionel, you should really take a capture on the server side. I'm seeing two possibilities. One is that the SSO doesn't support load balancing well, and that in H2 you get multiple requests in parallel going to different servers while in H1 they are very sequential. Another possibility is regarding to the header fields syntax as suggested by Jarno, but in 2.1 they're always lower case for both H1 and H2, so that cannot be the only difference. In both cases I encourage you to take a capture between haproxy and the servers to compare between a working client and a failing one. I'm pretty sure you'll spot a difference (missing cookie on a request, two requests going to different servers, etc). You can also post them here but be careful not to leave confidential information in them :-) Cheers, Willy
