title: How to prevent anauthorized use of website content?
body: <p>In the past our company had an agreement that a local news agency could embed some maps we had on our website. They would iFrame in the maps, and I'm told that we had some logic in place to prevent anyone other than the news site from doing the same thing (possibly via some kind of referral agent)?</p>
  
  <p>We recently have moved to our maps application being hosted on Amazon S3, and iFramed into our own page. The topic of preventing unauthorized embedding has popped up again.</p>
  
  <p>I do not have access to the previous code to see how this was done, but I'm assuming it was some sort of header check on the previous aspx page. Now that the map application is completely static on S3, I do not believe something like this would be possible.</p>
  
  <p>Could anyone weight in or point me in the direction of what I can search for? None of my searches have turned up anything useful (probably just using the wrong keywords).</p>
  
  <p>Thanks in advance!</p>
