Having URL without .aspx extension

Question

I noticed a lot of ASP .Net sites does not have the URL ending with ".aspx".

An example would be: - https://stackoverflow.com/questions

Did they create a Questions folder and put a Default.aspx inside?

In that case, wouldn't there be A LOT of default.aspx in many folders which is hard to maintain (even though it is user-friendly)?

Thanks y'all.

Answer 1

StackOverflow is written using ASP.NET MVC. The MVC framework does not use .aspx files.

The way it works internally is by using routing tables - see an overview here.

You can also do this with ASP.NET and .aspx files or you can use URL rewriting. You can read about the differences here.

Answer 2

You can refer to any URL rewriter or a routing technique for that. If you look at the new AS{.NET MVC, it works on that model only.
