asp.net - How do .NET sites hide .aspx extension of their files?

Question

I'm pretty sure stackoverflow.com is created with ASP.NET, but no matter where I click I see no .aspx extension in the address bar. How it is done and is there a particular reason for this?

Answer 1

In the case of stackoverflow, they use ASP.NET MVC rather than ASP.NET web forms. With web forms, the url is pointing to a file on your disk, while MVC is pointing to a controller action. If you're using webforms, you'd want to use URL rewriting. Scott Guthrie has a good article on doing URL rewriting.
