Good afternoon,
The connection timeout that is set in the HTTP Routing assertion is only the amount of time that the gateway will wait for a response. Devices between the gateway and the servers being connected to may have different connection timeouts that may be far more aggressive. Recommend that you gather a network dump at the gateway to see what the network is doing.
Some notes:
1) If you are doing posts through the HTTP routing, we recommend setting the retries to 0
2) For environments that have a very low SLA we recommend that the connection timeout be less than 500 ms
Sincerely,
Stephen Hughes
