SSL offload on Apache/Tomcat persistance and append issues

Hello all.



I'm not much of an ace when it comes to the F5 LTM's. I'm running version 10.something and I've been trying to get an application called "UNANET" (online time cards) functioning behind the load balancer.



I followed the Tomcat/Apache deployment manuals and it's a pretty straightforward setup. I have two virtual servers, one is an http that redirects to the https. I have an append rule that adds the complete path to the base url. (i.e. myserver - append /somedir/login)




My initial setup, which I believe had COOKIE as persistance, resulted in the login appearing not to work. If you typed the correct password, the application would just clear out the username and password fields but it would not display an error. Oddly, we discovered if you typed in the right FOLLOWED BY THE WRONG password suddenly the menu options for the application became available. I continued to toy around with different persistance options and I was unable to fix this.



I believe I changed the persistance option to universal and at that point upon logging in, the URL would change as if it were trying to authenticate the user,however the page would not load. If you clicked BACK and hit refresh, again the menu options would appear for the application.




My best guess here is that my append rule is not playing well with the paths of this application. I'm not sure if I need a more complex append irule to direct the client depending on the situation. Actually I'm pretty lossed.



Any insight you can provide would be greatly appreciated.
