title: www.Bo.lt, or how to make a copy a entire webpage including children files
body: <p>as you may have noticed service like Bo.lt allow you to edit a website and show the results.
  As far as I understood they make a copy of a website first</p>
  
  <p>like in <a href="http://lll.bo.lt/ev5ct" rel="nofollow">http://lll.bo.lt/ev5ct</a></p>
  
  <p>so, my question is, in order to achieve it, what's the best practice to pull all the page or  DOM form the page, and copy it to my server, including the children files?</p>
  
  <p>i know it sounds a big question, but i just need orientation if is doable in php / javascirpt</p>
