Hello James Shelton Agar,
We could recommend you the UrlRewrite module that Sitefinity has. We are using it both on telerik.com and sitefinity.com. The link which you have provided though is not related to the Sitefinity's UrlRewriter module. If you need further information it, please check the Sitefinity User Manual. There are some good examples there that should get you started.
Let us know if you need any further information.
All the best,
the Telerik team
