title: Fast redirect with background operations
body: <p>For a click tracking feature I need to create a hidden page that reads a $_GET or $_POST tag, saves it to database, does some data manipulation and redirects the user to another page.
  I want the redirect to be as fast as possible, and prefer to do the data manipulation after the redirect so that the user doesn't have to wait for it.</p>
  
  <p>What is the best method to do so? 
  The data manipulation actions are all background actions and have no user interface. 
  I thought of initiating an AJAX call to a php page and redirecting the user without waiting for the AJAX response. The called php file will perform the operations in the background.</p>
  
  <p>Will this work?
  Are there better alternatives?</p>
  
  <p>I'm using php and jQuery (with CakePHP), but I guess this relates to all languages.</p>
  
  <p>Many thanks in advance,</p>
