Hi,

 

With expiration set to 90 minutes the cookie will expire (so the persistency) after 90 minutes. Without a persistence record/cookie the BIG-IP will load balance the connection to 1 of your backend servers. If the user is lucky it will be the same server, if not you will get issues.

 

Why not use a session cookie (will be deleted when the browser is closed and least connection load balancing?

 

Cheers,
