New Post: How JQuery AJAX to WebService Returns ASPX page?

I want to pass a JQuery form data via AJAX to a web service for processing and instead of returning content via AJAX, I need to return a whole set of results via a full web page using a page template and XSLT.

I am comfortable with passing the data to a web service and processing it and send back AJAX updating the DOM, but I need to have Google recognize the URL change as a real results page and don't know how to do the following instead:

How do I go about passing AJAX received data to XSLT and getting a full web page postback within the response part back to the client?

eg: form with a few selectors >> AJAX to server >> Server processes >> Returns Results page to client with friendly URL incorporated ?

Thanks for any pointers you can give.
Martin.
