title: c# Port forwarding example
body: <p>So basically I have an URL blacklist, and in my project, i would need to use c# to listen to port 80 and redirect any request to those URLs to 127.0.0.1. </p>
  
  <p>I don't know much about networking.I've seen some topics on SO but don't quite understand them.  An example of it would be nice. Some explanation that comes along would even be better. </p>
  
  <p>Thank you</p>
