I am currently investigating a double request problem on my site. Not all the time, but sometimes, a requested page will in fact load twice...which is not a problem really until it is on a page with PHP that inserts stuff into my db on request (my tracking script).

I have read that an empty src in an image tag, and an empty url() in a css background could potentially cause the page to be requested twice.

However, I can't find any problems with those.

Is there anything else that could be causing something like this?
