Irule question about Hash persistence

Thanks for the reply.

 

I am using hash_persistence profile which references an irule.

 

I have multiple web applications being hosted by one LTM virtual server. The LTM virtual server is DNS A record. My web applications' are DNS alias. I only have one pool. I have two nodes (two web servers) in that pool. I can see that all the http connections are only on one node. I want to balance the load to two nodes. My understanding is that when I type the web app's URL on a client computer, DNS is resoved and find the public IP of the LTM virtual server. The LTM virtual server has a hash_persistence profile assigned. The hash_persistence profile has a Irule assigned. According to the Host Header in the Irule, http request is forwarding to pool. The Pool uses Round Robin method. The load should be balanced.

 

What is the criteria I want to use the persist clients? The web applications are dotnet apps. I want to make sure the users always communicate to the web app on one web server where he/she first lands on before he/she logs out.

 

 

Thanks
