Title: Simple Hit-Metering and Usage-Limiting for HTTP
Author(s): J. Mogul, P. Leach.
Status: PROPOSED STANDARD
Date: Oct 1997
Length: 85127
This document proposes a simple extension to HTTP, using a new "Meter" header, which permits a limited form of demographic information (colloquially called "hit-counts") to be reported by caches to origin servers, in a more efficient manner than the "cache-busting" techniques currently used. It also permits an origin server to control the number of times a cache uses a cached response, and outlines a technique that origin servers can use to capture referral information without "cache-busting."
