parse the query variable in default.asp using a
regular expression to extract the mattglet part

This is just a variation on custom error pages.
Hint, to get this going during development,
just do a Response.Write of the data so that
you can see what is happening.
using dns wildcards and this method, you can
even do h*tp://mattglet.example.com if you
wanted to.

They also claim it doesn't return an actual 404 header, but a 200 header so it would be useful for Search Engine friendly URLs... I run apache, so I've never done it. I assume you could set it to some PHP page as well... Pretty slick if it works, let me know how it goes.
