Suppose I were to build proxy server using squid with multiple accounts. Is there a way to determine how much data has been consumed by each account?
By data I mean total sum of all bytes which are sent as a result of a request. So if a webpage is requested, the count should include all bytes (images, html, js, flash, movies, etc).
I could not find it in the squid doc. Is there a programming hook I can use? Or another program?
