title: Node.js+Express running on port 80, infinite ads requests
body: <p>I've started a new project with node.js + express on Ubuntu EC2 at amazon.
  I've created an Express template and started the app with nodemon, but I've got a unexpected situation, when I run the project on port :3000 it works fine, but when I run it on port :80, it makes infinite requests to some yahoo advertising.</p>
  
  <p>Does anyone had a similar problem? or knows what's causing it? or knows how to fix it?</p>
