One of the coolest things about working at MSDN Magazine is the exposure I get to all the different technologies coming down the pipe from all over the company.  One of these that recently grabbed my attention was the set of enhancements that the IIS team has made in IIS 7.0 surrounding the "Integrated Pipeline".  If any of you have ever written an ISAPI filter in C (shudder), you will be particularly interested in this technology as it allows you to write the equivalent functionality by using ASP.NET HTTP modules!!

In the January issue of MSDN Magazine, Mike Volodarsky describes the pipeline in great detail and walks you through a sample where he adds ASP.NET functionality such as forms authentication and output caching to an existing PHP application - all without touching the existing application code!

Additionally, Mike has posted a follow-up on his blog - check it out!
