AltostratusBigIP persistence cookie changing in middle of session.
User goes to the login page, they will get the BIGIPServerPool cookie. Once they authenticate they will get the application cookie. As long as they keep on hitting the right server with the application cookie, everything will work fine. If they hit a different server with application cookie, it will result in Session Not Found/User not Authenticated error.
We are using Cookie persistence with default values (no expiration)
We set the following Cookie
Response sent 55 bytes of Cookie data: Set-Cookie: BIGipServerpool_app=3728940042.20480.0000; path=/
Then 4 or 5 requests later, the request now has
Request sent 95 bytes of Cookie data:
BIGipServerpool_app=3594722314.20480.0000
applicationcookie=bo5fhllsdbjgnmwstqroyp2j
I understand the additional application cookie but why did the BigIp cookie change? The session did not close and there is no expiration set.

Create an iRule to log the cookies going both directions. My guess is at some point the original BigIP cookie is getting removed by either the client or server.
Chris_Olson_172Thank you. I think that would be best. However, I am a network admin not proficient in irules. Can you PLEASE get me started with something you think will work?

DevBabuI believe the cookie is in the cookie insert mode. Doesn't matter if server removes the cookie. It's BIG-IP which inserts the cookie after it receives response back from server.
Could you try using oneconnect profile and check if that solves the issue.

Are you using 12 code? If so, did this happen before you loaded 12?

We are running 11.5.4. I expect this may be application related. However, the error "Session Not Found/User not Authenticated error" does not occur when we log on to the server directly; bypassing the F5.
