I never felt that you could ever justify caching in terms of bandwidth savings. You can only justify in terms of improving a users experience.

But TTLs will usually have to beset pretty low (2seconds) in order to do this and the technologies will haveto be catered toweb development environments (like cacheflow and ASP).[..] Hmm, if you cache what I suggest above, that's not really neccessary... No? Cheers, Chris -- Christian Kuhtz Architecture, BellSouth.net <ck () arch bellsouth net> -wk, <ck () gnu org> -hm Atlanta, GA "Speaking for myself only."
