Cookie Persistence not working

Hey,

 

We have cookie persistence configured on our BigIP LTM. We recently upgraded from v10.2.4 to v11.5.1 and the cookie persistence doesn't seem to be working as expected. Has anyone else had this issue.

 

ltm persistence cookie /Common/Cookie-Insert-Persist-New { always-send disabled app-service none cookie-encryption disabled cookie-name BIPcookie defaults-from /Common/cookie expiration 0 method insert override-connection-limit disabled

 

Thats the code for cookie persistence.
