Question & Answer


Question

Does Session Persistence have to be Enabled in Load Balancer for ICM Web?

Answer

Yes, session persistence has to be enabled because ICM Web is not cluster aware.?In other words, it is required for a Load Balancer to direct the user traffic to the same web server, given the session is still alive. On the other hand, Load Balancer should direct users to a different web server if that server ever goes down. The Load Balancer should be smart enough to detect/monitor the health of each web server on its own, and redirect the user session to a different web server if the designated one is dead.

Having session persistence "ON" doesn't mean all the load is always gong to the same server. It just means that the session (or user) will be hitting the same server, until the session is ended. There should not be any critical performance issue when it is "ON". It should even improve the performance as some user specific data would be cached in one single web server.

This only applies to on-premise installations
