-----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. - -P -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMUgqXDt40Y2EitWtAQE2EQQAoetBe/oW0QPziKeYjYoSsANu+sYfTv8g KuJCwNpEPkGsG/YhBNJp19oq9a0GHF5rtLe6FMypqrRsZEoOWUWBQDelrM+WdrAL 9sdYnhJMRLwG4tQcUvIqsECDf8x0q105AJ0sSICeVPbBoNg205HtFskdT16rSP01 jMmQR8DsU4A= =9YiX -----END PGP SIGNATURE-----
