Permalinks in ASP.NET

Can anyone point me to some good resour开发者_StackOverflow社区ces on how to implement PERMA links in ASP.NET?

I've done a couple google searches but haven't found anything that like authoritative or definitive.

There's an example of a Permalink Generator for ASP.NET MVC in Brad Wilson's Big Boy MVC Series - even if you're not using the MVC framework, it probably can give you a good idea of what you need to do to generate permalinks.
