title: Directly open colorbox when entering through external link
body: <p>Dear stackoverflowers,</p>
  
  <p>I have a website in which you can open a page (with id) in an colorbox with iframe = true.
  in this iframe (colorbox is opened) you can hit a facebook like button. In the meta data of the facebook like button, you can set a url which will be opened when clicking the article from your facebook.</p>
  
  <p>What I want is the following: When someone clicks on the article on facebook, you will be lead back to the url set in the meta data of the FB like button. Right now, it opens the url, but not in a colorbox. I want this url to automatically open a colorbox.</p>
  
  <p>So is it possible to directly open a colorbox when entering it from a external link?</p>
