Hi everybody,
I have been running Tomcat on production for a few years with no problem
but now, after moving to a new company, I am completely unable to get
session stickyness working.
The setup is as follows:
Apache 2.2.3 (CentOS 5.4 version) -> Tomcat 6.0.24.
I have tried all of mod_proxy, mod_ajp_proxy and mod_jk but, no matter
what I do, I can not get Apache to always send the requests to the
Tomcat specified in the jsession.
Firebug indicates that the JSESSIONID cookie is being set as it should
but it still sees requests going to the other server. I have also tried
changing the jvmRoute to exactly match the worker name for mod_jk but it
still doesn't work.
I would appreciate any help, as I am stuck.
Here are the configurations I have tried. Obviously, only of them is
active at any given time. httpd.conf is the standard one from the CentOS
RPM.
Tomcats:
All of them have a jvmRoute of pub-app0X, where X goes from 1 to 5.
