I need to implement https support for <int-http:outbound-gateway>.

Following is the scenario:

There is <int-http:inbound-gateway> which accepts inbound url to Spring integration. The reply-channel of <int-http:inbound-gateway> and <int-http:outbound-gateway> are same. Based on the HeaderValueRouter, the inbound request is forwarded from request-channel of <int-http:inbound-gateway> to request channel of <int-http:inbound-gateway> . Now response is received from the outbound url and put in the reply-channel. The url-expression of <int-http:outbound-gateway> is built from the MesssageHeader "http_requestUrl" attribute.

Now if I host the external app in https. What configuration I need to make in <int-http:inbound-gateway> to get the response in reply-channel
