title: How to create a simple c# http monitor/blocker?
body: <p>I was reading that question (<a href="https://stackoverflow.com/questions/226784/how-to-create-a-simple-proxy-in-c">How to create a simple proxy in C#?</a>) that is near of my wishes.</p>
  
  <p>I simply want develop a c# app that, by example, monitors Firefox, IE, etc and logs all navigated pages. Depending of the visited page, I want to block the site (like a parental filter).</p>
  
  <p>Code snippets/samples are good, but if you can just tell me some direction of that classes to use I will be grateful. :-)</p>
