IIS7和Vista上的ASP .NET 2的URL重写问题

I've got a website running under ASP .NET 2/IIS7/Vista. I have a URL rewriting module which allows me to have extensionless URLs.

I have also added the URL rewrite module to the modules section and set runAllManagedModulesForAllRequests to true.I've got a website running under ASP .NET 2/IIS
