proxy-xi-webservice

Hi

I have a synchronous scenario (proxy-xi-webservice) where I got to send the request from proxy to particular webservice (one webservice out of available 3 webservices) on the basis of target URL which is available in the payload. Once we route the request to the particular webservice, the response should be routed back to proxy through XI. Is this scenario possible without BPM ?? Can we do this scenario by using logical routing (through context objects) ?? Is there any other alternative solution available to this problem ??

Thanks
