A connection failure occurs when a pool member picked by cookie persistence goes down.


Connection failure. The BIG-IP system tries to persist to the pool member that's down.


-- Configure cookie persistence. -- Make a connection to get a cookie. -- Force the pool member down. -- Make a connection with the same cookie.



Fix Information

Auto reselection for cookie persistence now works when a pool member picked by cookie persistence goes down, so there is no longer a connection failure.

Behavior Change

Previous behavior: The cookie is not deleted when reselecting a pool member. New behavior: The BIG-IP system removes cookie persistence for the server-side traffic when pool-member reselect fails (e.g., Connection Limit)
