Imagine a cached image that is referenced from all pages of a web site and all 
pages have a relative expire date.

Browsing around will lead to strange results there, i.e. as long as no page is 
visited twice and the time between two page views is less than the (relative) 
expire time, such an image will never be reloaded.

A similar problem arises if the document is not cached at all:
The document's cache creation date will be set to time(0) every time it is 
loaded, so images in that page will never expire as long as the page is 
viewed frequently enough.
It would break all pages with pragma no-cache but a relative expire date 
(which should affect the contained images). And I've seen such pages often 
enough.

If you still aren't convinced,
please tell me _why_ you think my idea is wrong.
After all, we agree on how to handle absolute expire dates.

Cheers,
Tobias
