If you're using mod_proxy you need to put: stickysession=JSESSIONID|jsessionid to ensure you're capturing both the URL encoded and cookie based session ids. Unfortunately, because RHEL/Centos insist on deploying HTTPD with the version number set when they released the OS, it's virtually impossible to tell whether your HTTP is actually 2.2.3, or 2.2.3 + important fixes, additions etc from 2.2.(n > 3). mod_proxy_ajp was first released in 2.2.3 for example, and many improvements occurred in later releases. p
