Need a quick fix to visitor counter code (Javascript/AJAX)

Project Description:
I need someone who can quickly fix hit counter code (which currently allows only synchronous tracking) to make it work Asynchronously.

If you don't understand what I'm talking about above please DO NOT bid.

Only bid if you understand how frontend side of asynchronous tracking counter works in Javascript / AJAX.

This should be a pretty straightforward if you're already familiar with this stuff.

You must leave me a message with the word "SPOF" on top of the message so I know you've read and understand this.

Thanks.
