Hi John ,
I too have a similar scenario, where I have to insert two parameters in the HTTP response.
I am planning to write a custom module for it and just call the module before sending the response.
I am not sure of how can I access both the body and header and alter the header and send the final HTTP Response and Body back to the sender.
I am using a Rest Sender Adapter : HTTP protocol and a SOAP receiver. Its a synchronous call.
Have raised the question on SCN too, but your post seemed quite similar to mine.
If you could throw some light, would be quite helpful.
Thanks,
Pragya
