ie cache

Can anyone please tell me what a value of Expires=None in
IE cache means? If you view the files under Tools:Internet
Options:Settings:View Files.
 
This header identifies the date/time the data should be considered stale.
This header is often used by caching client.

What I read from this is that if the data has expired a new page will be
downloaded. Otherwise the page in the cache will be used.

However this filed is often ignored by the caching application.

p.s. Part of this text is from HTML Unleashed book.
