Did you know IE8B1 can do one thing other browsers can’t?

I’m just figuring out how to detect Flash Player on server side. Seems like Firefox 3.0.1 doesn’t send any header identifying FP, Opera 9.50 - exactly the same. And IE8B1? Gives nice x-flash-version and even Referer pointing to SWF file! I think I like IE8 even more now… EOT.
