Java Detector

This handy script detects whether the browser has a Java plugin enabled and redirects accordingly. It works with will main browser manufacturers and has been tested in Opera 9, Netscape Navigator 8.1, Mozilla Firefox 1.5.0.4 and Internet Explorer 6 SP2. It is particularly useful if you intend to run a Java applet as it can redirect non Java users to an alternate page, so they are not staring at a blank page.
