You have an excellent breakdown of all the possible solutions here: http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

Which version of IIS are you using? For IIS7 use its own URL Rewrite Module, and for II6 use Intelligencia UrlRewriter.NET: http://urlrewriter.net/
