Summary

0026846: Code running on tomcat start to search in remote tomcats is not needed anymore and can't work with Load Balanced Tomcats

Description

There is code added in issue 10309 is running on every tomcat start and checks any row from ad_session marked as still active. And then tries to connect to the tomcat which was running that session (remotely via http) to check if that remote session is still really alive and set it to inactive otherwise.

By design that code relies on the url of the tomcat running that session to be correct inside some ad_session column.

Now when running 2 tomcat's in 1 installation which are access by a load balancer then the url in that ad_session column is the common url of the load-balancer and not anymore the url of the individual tomcat.

That breaks this added code completely and the start check will try to reach 'some' unknown tomcat (as decided by balancer) instead of the one owning the session.

However this added code is not needed anymore at all after issue 11039 has been fixed (which was long time ago (2009).

So this change (after verifying this claims) just be removed.

Steps To Reproduce

Run 2 tomcat in 1 install behind a load-balancer and notice url stored in ad_session is the load-balancer url
