When I try to pass parameters in url I used GET to do so, but I noticed that facebook and some other sites passing variables by building url in different way like this "facebook.com/user1". I think "user1" is passed and there is no real directory named "user1" in facebook.com base directory.
how to use "mysite.com/user1" instead of "mysite.com/?user=user1" to maintain user id, without creating a directory named "user1" in base directory?
Programming language: C#. IIS version: 7.5
Thanks in advance.
