I have a situation where I need to do a Server.Transfer to a page that has in the past worked with request parameters. <BR><BR>Basically the situation is I have a URL w/o querystring (something.com/ProductID/1234), the URL gets parsed and then must be sent to a page like productDetails.aspx?id=1234. Using a Response.Redirect is out of the question because of search engine inclusion issues.<BR><BR>So where things fall apart is that I cannot add to the Request.QueryString because it is read-only. I've thought about using the Session to pass in this info (and have successfully done this on another page), but this particular page I'm forwarding to has a ton of user controls that already depend on the request parameters. So without making a bunch of changes, is there any way around adding to the query string?
