cache-busting document

Hi,

This is some work which has been going on in TERENA's task force on
WWW caching (see <URL:http://www.terena.nl/projects/choc/>) to
document how HTTP servers may be friendly towards caches.  We're 
looking for comments and feedback, and were also wondering whether 
people thought it might be a good idea to put this out as an RFC.

Cheerio,

Martin
