IIS5-like verb filter in IIS6

[Brian]

I have an ASP.NET 1.1 application that does URL rewriting via a custom
HttpModule. We recently migrated this application from Win2k/IIS5 to
Win2k3/IIS6. In IIS5, I added a wildcard application map that filtered
the verbs I wanted to handle. In IIS6, the wildcard application is
added differently and it doesn't allow for verb filtering. How can I do
the same sort of filtering in IIS6?

Thanks!
