Prevent IE from viewing my website?

Question

I'd like to take elitism to the n-th degree by not allowing Internet Explorer to browse my website.

Is there a way to do such a thing? My website is built upon the CakePHP framework, if that helps.

Answer 1

I'm pretty sure all IE versions support the following - does require JavaScript though.

<!--[if IE]>
<script type="text/javascript">
window.location = "http://www.google.co.uk/chrome"
</script>
<![endif]-->

If you want to do it in PHP, you can use the $_SERVER['HTTP_USER_AGENT'] variable to read in the user agent and then look to see if it's using IE, and stop loading if so. You'd want to use a regex on the string, with a simple example being:

if (preg_match("Internet Explorer", $_SERVER['HTTP_USER_AGENT']) == 0) {
    // print message or whatever and abort
}
