I'm trying myself to sort out the browser cachine, proxy caching, encrypted pages
cached in browsers but not in proxies, pages cached but requiring revalidation, etc.
Confusing!
I recommend starting with the Caching Tutorial at
http://www.stars.com/Internet/Cache/
then check out his references at the end, particularly the W3C's description of
caching in HTTP 1.1.
best,
Chris Norloff
