Hi All, Following is the log for a client request to my proxy service with wire-log enabled. BE response is logged by the LogMediator in the proxy service's out-sequence. But the response to the client doesn't contain the response body, only contains the HTTP 200 response header. Any tips to tackle the issue is much appreciated.
Thanks, Dileepa [1] [2015-02-10 23:05:21,381] DEBUG - wire >> "POST /services/StanbolProxy HTTP/1.1[\r][\n]" [2015-02-10 23:05:21,384] DEBUG - wire >> "Content-Type: text/plain[\r][\n]" [2015-02-10 23:05:21,384] DEBUG -
