Hi Werner,

 

since the HTTP_REQUEST event was complaining, I do strongly believe its a client side connection termination, because a server side connection isn't utilized yet.

BTW: Your posted iRule contains a logic, that could exhaust all of your available memory very quickly. Did you already experienced memory problems in the past or during those events?

 

Cheers, Kai
