Richard Heyes has posted a quick script to help you tailor your site to the browser a viewer is using.

If you ever wanted some browser detecion code, here it is. It works along the same lines as the Ultimate Javascript Client Side Detector, however it's server side. It doesn't pollute the global namespace (much), and it's very simple. Just include the code and call the function. Easy.

The code is as simple to use as an include and a call to the GetUserAgent function to get what you need. You can download the script here.
