Cookie persistency problem on ACE module

Hello,

I have an ACE20-MOD-K9 with version  A2_3_6a, and i am having problems in cookie persistency. the setup contains 4 servers using round-robin algorithm and cookie persistency and that receive http traffic on port 9090. I have been receiving complains that the users are getting disconnected randomly while accessing the web application through ACE. Below is part of the config, i hope someone can shed somelight if there is any thing missing.

Note: when setting the timeout of the cookie to default or something equal to hours, the disconnection/complains gets worse.

I cannot use persistency based on ip address.

Through my research, I did not find anything that help me although i believe it is a bug but i cannot confirm it and i also cannot upgrade later that A2.3.6 on ACE20.

Kindly I appreciate any support.

Regards,

George

Hi,

Try with the sticky group configured like this:

sticky http-cookie WRKFLW GROUP1

  cookie insert browser-expire

  replicate sticky

  serverfarm WORKFLOW_SVRs
