Re: Does load balancing with sticky sessions work with mod_jk? - SOLVED
I've been digging around in the source for Tomcat 4.1.27, and this is what I've found. The problem I've had with not being able to get load balancing to work in my application is a problem with Basic Authentication. Since Basic authentication never sends a JSESSIONID cookie, the jvmRoute is never available to mod_jk. This issue was obscured by the fact that I was using the SingleSignOn valve. This facility creates its own cookie JSESSIONIDSSO. This cookie also doesn't have the jvrRoute attached and that sent me on a wild goose chase through the wrong code. I've reworked my app to support FORM authentication even thought this requires a form for each servlet context and extra JkMount points. Thanks to Chris Daniluk for setting me on the right track. G.

Once you pointed it out, I realized that the jvmRoute was not on the end of the cookie. Looking in the mod_jk source, I can't find anywhere the '*SSO' cookie is used. It would not have been read, even if it had been sent. I'm doing further research. I'll post what I find. Thanks for all of your help so far. G.

I'll attempt the compile. I did verify that the worker names in workers.properties and jvmRoute do match. Thanks again. G.
