IIS 7 Express on VS 2010 Win 7

I'm writing some http handlers using vs 2010 on a win 7 virtual machine. I have not been able to discover how to configure the mappings for particular extensions and verbs using IIS 7 Express. For example

extension = Foo

Executable = ../aspnet_isapi.dll

Verbs = get, head, post

Does a开发者_JS百科nyone know where I might find that info?

Q: Does IIS Express use the same configuration system as IIS 7.x?

A: Yes, IIS Express uses the same applicationhost.config and web.config files supported by IIS 7.x. The key difference is that with IIS Express, the configuration is maintained on a per-user basis. In particular, whereas IIS has a global “applicationhost.config” file, IIS Express maintains a user-specific “applicationhost.config” file in the %userprofile%\documents\IISexpress\config” folder. This lets a standard user run IIS Express and also lets multiple users work on the same machine independently, without conflicting with each other. Some settings require Administrator user rights to set and modify (see question above about running as a standard user).
