I'd remove "Pragma: no-cache". It's just voodoo programing, and has
no effect except to perpetuate the myth that it *does* something. And
the parameter of "Expires:" I believe has to be an actual date/time,
not just a 0. And, to hit 3-for-3 here, I dunno if it's a typo, but
you need "no-cache" on that "Cache-control". :)
