Assuming $xtype is defined correctly somewhere, I reckon IE is choking on
the Content-Transfer-Encoding header. This is a MIME header -- it doesn't
belong in an HTTP response at all. Go and read RFC 2616 some time.

You don't need to cast $filesize to a string -- PHP will do this for you
anyway. And while you're at it, I suggest you replace the while() loop with
a readfile() statement instead (<http://uk.php.net/readfile>).

Oh, by the way, filesize() is another useful function. That way you can get
rid of the fopen and fclose instructions altogether.
