Creating an ISAPI Filter To Filter Web Content   

I'm trying to develop a web filtering system for the school i work at.
We have an ISA 2004 server, so I know I need to write an ISAPI filter to 
capture the web content.
Once captured I will then scan for unsuitable words/phrases and return a 
blocked page... or the content if ok.
So, bearing in mind I only know VB.Net, how do I go about creating such an 
ISAPI filter and how do I use it to communicate with a database (SQL 2005 
Express)?

Pointers and sample code much appreciated

Re: Creating an ISAPI Filter To Filter Web Content   

Not meaning to be arrogant nor demeaning, but given your stated
background and intentions, I suggest evaluating, purchasing, and
deploying appropriate commercial content-filtering software.

You will have to know how to write performant, security-minded, crash-
free, and memory-leak-free server-quality C code. It will be
manipulating and buffering raw data streams, caching SQL queries, and
efficiently scanning data.

If the above sounds like something that you can independently produce
with "pointers and sample code", then please indicate agreement.
