To change this behaviour you need to either enable "TCP server reuse" or "persistence-rebalance". This is documented in the ACE Server Loadbalancing manual under "Configuring HTTP Header Insertion". Admittedly this is a little subtle as the manual only mentions later (for example under TCP Server Reuse that "... Another effect of TCP server reuse is that header insertion and cookie insertion, if enabled, occur for every request instead of only the first request." - and similarly under persistence-rebalance.
Okay, but where does the timeout of 1 minute in itself come from?
It could be that a user's session is balanced to another server, resulting in a new session and thus a new insertion, but we configured our serverfarms to use sticky sessions with a timeout of 15 minutes so that shouldn't be happening.
The fact that the insertion only works on the first request isn't our biggest problem, what bothers us more is that we're receiving complaints that customers on our websites lose their session after a minute of inactivity, resulting in an empty shopping basket, being logged out, etc.
