Description
I have found that if the HTTPConnector times out without receiving the response from the backend API, then somewhere down the line it generates 2 error responses and this is evident from the metrics as it show 2 failures as supposed to 1 failure for the single request.
So there are 2 issues,
- firstly the returned error response contains 2 error XMLs appended to each other and sent to the browser and hence not a valid XML.
- The metrics also shows as 2 failure response for single request.
This can be easily simulated by setting very low timeouts (for ex: 2 secs) in apiman.properties.
apiman-gateway.connector-factory.http.timeouts.read=2 apiman-gateway.connector-factory.http.timeouts.write=2
