Hi again, the persistence will remain until the time specified in the farm
option:
*Source IP Address Persistence time to limit **in secs, only for IP
persistence
*.*
which by default is 140 secs. So it's the right behavior. In order to work
around your problem, you could increase that timeout at the same value as
the HTTP persistence is set in your real servers/web application.
The L4 farm has nothing to do with your browser so the behavior will be the
same and the persistence will wait until the timeout although the user has
logged out from the web application.
