Hi,

        I may be terribly mistaken, but I think that this to some extent has
been discussed previously on Bugtraq. I cannot get through to the securityfocus
web site all morning so pls excuse me for not quoting the exact post where this
was mentioned the first time.

        Quoting from memory, so excuse me for any discrepancies with the
original post (it was more than 6 months ago): IE ignores not just the
extension. If I recall correctly mime types supplied by a server are happily
ignored as well.

        What happens is IE looks at the first 200 bytes or so and desides based
on "magic" first, looks the mime type/extension later. So it is not just HTML.

Also IE runs some programs looking just for "extention" like Word or Excel files.
The another bug (in version 5.0 or 5.5, not in 4.5) is implementation for viewing/editing Word (.doc) files. Of course 
IE runs Word no mather is MIME for executables or jpeg. Program will return error and die when you click on "back" 
button.
