oh and the other thing is that most browsers can pretend to be something else. and often fo about in disguise so that they will be let into obscure sites that have fscked policies like you want to implement. how are you going to tell which browsers are genuinely telling you their identity?
Well, IE mostly has trouble with disguising itself, and those who use browers that are set up to disguise themself are safe, and the user mostly will know enough to know that the message is not for them.
No more of this madness, just make standards compliant pages and tell people with a banner that proclaims your site html standards compliant.
But the author has an agenda, that nobody should visit his site if they use the Internet Explorer.
