I had to do a few hours work to make sure I properly understand how to rip apart the URL that invoked my code, so I figured I might as well share it with you, too. A helpful diagram is attached.

You have permission to use this diagram for personal purposes, but not for any profit-making purpose. I ask only that you post any errors you may find so I can update the diagram. Thanks.
