How to do URL-rewrite with ASP.NET?

To have the .aspx-prefix at the end and a lot of querystring parameters at the end of the URLs feels rather ungraceful. And it's not any good from a SEO-point of view. IIS 6 and ASP.NET has not got any good built in solution to do URL rewrite. But there are some solutions and I will collect a few links here that I read on the subject.

In Ruby on Rails URL-rewrite seems simple and is a natural part of the language. On Apache servers there are the mod_rewrite module which is great for all the PHP-developers.

With ASP.NET it's possible to use HttpContext.RewritePatt, but it's not as simple as it first appears. I found a lot of articles about soultiuons but many of them described problems with cacheing, themes and problems with Postback.

On Urlrewriting.net there's an open source component that claimes to have solved a lot of these problems. I have not tried this myself though.

I have also read about the coming IIS 7.0 and that there will be a better support for URL rewrite. Lets hope so!
