I am trying to study user interface usage based on links clicked, so I attached a pingback to the click event of every link. It simply does a basic $.get(url) to the statistic tracking script on the server. However, I have noticed during my tests of this rather simple code that a LOT of my pingbacks aren't getting received unless I have set AJAX to make synchronous requests. This ties up the browser unless the server responds back though. I would like to just send the request and be done with it since I do not need to process the response in the browser.
What could be interrupting the transmission here?
