Datapower Soap Envelope Header Values from Request

Question

I am having a WS Proxy in Datapower . Both the client and the backends are HTTP . My request contains a soap header that has values like : wsa:Action wsa:MessageID wsa:ReplyTo timestamp

The backend doesnt require all these values , so they are stripped of before sending a cnverted request to the backend and obviously these are not there in the response which I get back from backend. Now when I send a response back to the client from Datapower , I need all these values back in the response soap headers . A

newly created timestamp which expires after 5 mins . Action MessageID ReplyTo

Is there any way to put them back. I dont want to do it from xslt , as I beleive there is some inbuilt support from Datapower to handle this .

I would just store the entire SOAP-header node-set in a context variable and replace it in the response rule. Unless, of course the back-end adds or modifies specific values. In that case, you can pick and choose what to restore.
