I presume this expiry time/date is set differently depending on the type of page? (very low for a forum like this) and high(er) for less dynamic pages)?

Or is it just based on recent 'refresh rates'?
Believe me - you would not believe how complicated it is for a proxy to determine if it's copy is current ("fresh"). There are pages and pages of specifications and http headers to control it.

Sorry, I don't follow what you are saying. Can you explain ?
