Uh-uh. Think about it. 

* The "Refresh" directive says: "Reload me again--NOW!!!! AND YOU'D BETTER
  OBEY THE REFRESH DIRECTIVE ON THE RELOADED COPY TOO!!!!!!"

* The "Expires" directive says: "I'm out of date, so If somebody asks for me 
again, you'll need to reload me at that point."

Do you see the difference? And why the "Refresh" CONTENT="0" tag messes up
your browser while "Expires" doesn't? And why the "Refresh" tag annoys the
hell out of people with metered ISDN lines who have to turn off the auto-
dialing feature of their ISDN modems because stupid web pages try to update 
themselves every so often and run up the phone bill in the process?

Shimpei.
