OWA redirects with URL rewriting

From the “you learn something new every day, whether you want to or not” file: there’s an IIS extension that lets you doURL rewriting. Chris Lehr has a blog post explaining how to use it to send users to the correct OWA virtual directory no matter what (or almost no matter what) URL they enter. This is a lot cleaner than the other methods I’ve seen described in the past.
