How do you program URLs without file extensions (like myspace.com/username)?

Question

I code with C# .NET, HTML and javascript, and all my web pages end in .aspx. What kind of page doesn't have an extension?

Answer 1

By not using a page as the link. Link to the folder that contains the page, and have the page named as index.htm, or whatever extension the page requires.

Answer 2

not a page, but a directory. Directories (or folders) do not have extensions. They do have an index.html page INSIDE the folder that the user sees when they navigate to your link.

that illustration folder has an index page inside that the browser automatically loads. without the index.htm file you'd see an error.
