SharePoint Website Schematic

I find myself drawing the same diagram over and over again in meetings to explain how SharePoint sites relate to IIS web sites, how managed paths and alternate access mappings fit and why you need to extend the SharePoint web application if you want more than one authentication provider.

After some of my colleagues pestered me to draw it again, I decided to create an electronic version, and since everybody seems to find it so useful I thought I'd post it here as well.

Rather than talk about it, I'm going to post it 'blind' and invite comments from you, my enthusiastic audience as to how easy it is to understand and any errors or omissions there may be.

With a little luck, somebody will find it useful!
