IE8 window.location HTTP_REFERER

Stupid HTTP variable, HTTP_REFERER. It's spelt wrong for a start.

Anyway, to cut a long, stupid story short, an HTTP call invoked from a javascript window.location change will usually set the HTTP_REFERER variable on IIS because the browser sends a Referer header.

I say 'usually' because it DOESN'T FRIGGING WORK in IE8. IE9, FF, Chrome, fine. IE8, nope.

Sigh.
