Url redirecting

Hi,
When I try to redirect to some url using pub.client:http service, it redirects to url as:

http://IPaddress/invoke/test1

but i want to redirect it to some domain like http://www.yahoo.com. This url I am providing in the url of serviceIn of pub.client:http service.

I have a output template which has a meta tag to redirect when service completes.

Thanks
