This bit confused the hell out of me.  Like Martin Atkins (no relation...
probably) suggested, whenever someone's auth is bad for whatever reason I
redirect them to the login page, possibly with an error message explaining
what went wrong.

I would never have imagined trying to solve this problem at the level you're
suggesting, nor do I think it is particularly necessary, since every server
side language can do a redirect by themselves.
