Remember, you can't prevent anything. This is the #1 thing that web creators seem to be not able to understand: Once that page leaves your server, it's outta your hands. You don't know who's going to render it, or cache it, or index it, or whatever.

Basically, my point is, the cache things are suggestions at best. Nobody enforces them, and Lord only knows what mutant and/or broken browsers might be out there.
