title: 2 sites sharing one web application pool? when should this be used?
body: <p>I just did a simple experiment. I created one web application pool in my local IIS, then I made 2 web sites point to the same app pool. Web sites are NOT virtual. and of course, they function OK locally.</p>
  
  <p>When should we start using shared app pools? And under what circumstances should you ever share an app pool between 2 web sites?</p>
