Hi Klaus, in fact now I think I was wrong since RFC3261 says in "16.7 Proxy - 
Response Processing":

  6.  Choosing the best response

         A stateful proxy MUST send a final response to a response
         context's server transaction if no final responses have been
         immediately forwarded by the above rules and all client
         transactions in this response context have been terminated.

         The stateful proxy MUST choose the "best" final response among
         those received and stored in the response context.

         If there are no final responses in the context, the proxy MUST
         send a 408 (Request Timeout) response to the server
         transaction.

Well, it's not neccesary to do that, you can do it in failure_route :)


Thanks.
