This page exists for the sole purpose of redirecting the user back to the KAB homepage whenever a page that does not exists is attempted to navigate to. when this happens the script at the top of the page executes replacing the current page with the home page. this looks nicer than having a 404 file not found error message appear. This wordy description is included here because, apparently certain versions of IE will not execute the script if the page content is below 1K or 512B, I could not get a susinct answer to that.
