How can I block site visitors using legacy browsers

I want my site to block access to visitors that are using outdated browsers such as IE6 and IE7 etc.

I am looking for a script that I can use to block certain browsers accessing my site

You can detect older versions of Internet Explorer using the IE Conditional Comments feature. The following snippet when included in a web page will redirect versions older than IE 8 to a separate page -

<!--[if lt IE 8]>
<SCRIPT LANGUAGE="javascript">
location.href="legacy.html";
</SCRIPT>
<![endif]-->

You can also choose to hide the page's content by setting the container tag's display property style to none via JavaScript.

The browser can also be detected through server-side code.
