This is a list of interview questions for ASP.Net programmers that Scott

This is a good list. Everyone should know these.

  things can you do at each?

• What are ASHX files?  What are Handlers?  Where can they
  be configured?

• What is needed to configure a new extension for use in ASP.NET? For
  example, what if I wanted my system to serve AS PX files with a *.JP extension?
