HTTP response timeout

Hello Aaron (Hoolio), I have tested your example and it works. However, it doesn't cover exactly what requested: in fact the HTTP response for timeout too long should be sent by BIGIP if a timer of 1 sec expires and the real server doesn't send the answer. In your example the irule is instead triggered when the BIGIP receives the answer by the server. I think we should use a timeout event but I can't find anything like this. Do you have any idea ? Thank you very much for your help. Mario
