session cookie persistence question

Hi Jayson,

Are you using a cookie insert persistence profile with the expire time set to 0 (session)? If so, the client should send the cookie on each request as long as the browser is kept open. One common issue with layer 7 based persistence is that you need to apply a OneConnect profile to the virtual server. This ensures that LTM will make a load balancing/persistence decision on each HTTP request. If you're using serverside source address translation (SNAT), you can use the default OneConnect profile with a /0 source mask. If you're not using SNAT, then create a custom OneConnect profile with the source mask set to /32. See this wiki page for details:

If you're already using OneConnect or adding a OneConnect profile to the virtual server doesn't fix the issue, can you try reproducing the issue with a browser plugin like Fiddler2 or HttpWatch to see what the client is sending? You can also use an iRule to log debug messages on the persistence and load balancing decisions:
