Using spring integration as a mediator -


i try use spring integration simple mediator. have webapp residing on intranet can not accessed outside. want expose app through mediator in dmz. means url:s http://gateway/theapp/* should forwarded http://internal/theapp/*. simple in theory seems component handling outgoing http-reuests in spring integration (httprequestexecutingmessagehandler) needs explicut uri, i.e no wildcard matching. can achieved spring integration?

the inbound gateway puts url header; can use expression on outbound gateway...

url-expression="headers['http_requesturl'].replace('gateway', 'internal')"

if using java @configuration, can use constructor takes expression...

expression expression = new spelexpressionparser().parseexpression(     "headers['http_requesturl'].replace('gateway', 'internal')");

this test case similar grabbing query string , appends new url.

in case, puts query string in payload; added header instead (e.g. post), using <int:header/> child element.
