title: jQuery Ajax call with no results expected
body: <p>I'm trying to collect some stats on some clicking events happening on my webpage.</p>
  
  <p>I figured I would add an onmouse event to the links I want to track, and trigger an ajax call to my tracking php script.</p>
  
  <p>What would be the most efficient way to do that, knowing that I don't expect anything in return, and that things should go on normally even if it fails?</p>
  
  <p>I know there are some special HTTP calls when you don't expect any data back. What is it exactly? Does jQuery support it? What about my php script, should it return a special HTTP header?</p>
  
  <p>Any advice to make this efficient is welcomed.</p>
  
  <p>Thanks</p>
