title: How do determine if a site uses amazon's web services?
body: <p>Is there any way to tell if a website uses amazon's web services, or are all the API calls hidden after the browser renders the code?</p>
  
  <p>I am trying to figure out if this website uses amazon's web services.</p>
  
  <p><a href="http://www.toms.com/" rel="nofollow">http://www.toms.com/</a></p>
  
  <p>I did a search on the source in the homepage on "cloudfront" and it came up, but that was in the javascript, hehe.</p>
  
  <p>I know the rest of the site is in php/mysql.  So I suspect that the API calls were done in php which causes the calls to be hidden when they're rendered.</p>
