URL Routing in ASP.Net Web Forms Part - 3 - URL Routing versus URL Rewriting

ASP.NET routing differs from URL rewriting. URL rewriting processes incoming requests by actually changing the URL before it sends the request to the Web page. For example, an application that uses URL rewriting might change a URL from /Products/Widgets/ to /Products.aspx?id=4. Also, URL rewriting typically does not have an API for creating URLs that are based on your patterns. In URL rewriting, if you change a URL pattern, you must manually update all hyperlinks that contain the original URL.

With ASP.NET routing, the URL is not changed when an incoming request is handled, because routing can extract values from the URL. When you have to create a URL, you pass parameter values into a method that generates the URL for you. To change the URL pattern, you change it in one location, and all the links that you create in the application that are based on that pattern will automatically use the new pattern.

Thanks and Regards,
