Re: Another Cache-control: proposal

-----BEGIN PGP SIGNED MESSAGE-----

In a previous episode...Jeffrey Mogul said:

- -> Specifically, I'd propose using:
- -> 	Cache-control: max-uses=NNNN
- -> on responses, where NNNN is a positive integer.

To summarize, we're talking about a token system, where the cache is
given N tokens to use however it sees fit (1 token to serve a page to
a client, or it can redistribute its tokens to other caches).

This has multiple advantages over the "take and cache the page now, but
report a summary back to me later" scheme. It guarantees the number
of transactions is <= the current scheme of not caching these pages,
while the other proposal can actually generate 2 transactions for one
page (1 to get, 1 to report.. none served from the cache). Also the
web server does not need to be available at two distinct times with
Jeff's proposal.

I am not a demographics expert, but it would seem to me that a sample
size of 1 in 8 or 1 in 12 is more than sufficient for statistical
purposes, and the bandwidth and server load savings are tremendous.
