headers

I have an application (a widget) where I use $.getScript() on a 5 minute timer, loading a file every five minutes. I then take the contents of the file I just downloaded, and rebuild my page, so that my widget can update. Most of the time, however, the file is unchanged, and firebug displays a 304 Not Modified header every 5 minutes, as my timer executes $.getScript().

I would like to sense when the file is not modified, so that I don't use up user resources, rebuilding the page for no reason.

Is it possible to obtain html headers when using $.getScript()?
