Call another web service from incoming credential

Hi there,

I have a service which will be invoked by a DSP page hosted on the same IS. And in this service, I need to call a web service hosted on third-party application. And now, I need to use the same username/password to call the DSP as well as the third-party web service, so is there a way to get the incoming credential from the service and then use it to call the third-party web service? thanks a lot.

It works now, I passed the incoming Authorization String to the outcoming requestHeader and it worked.
