Re: [squid-users] Fwd: Howto Measure bandwidth consumption of HTTPS traffic?

Amos and Sir June -- Thanks for the reply. I have a couple more questions.

Sir June -- Can you actually get a protocol breakdown and user
breakdown from monitoring ETH0 and using MRTG?

Amos -- Great tip. Will the log change that you suggested accurately
capture all HTTPS traffic from the client to the internet server? I
assume that all HTTPS traffic is routed through the proxy. i.e. If the
client send 1 mb of data to Gmail, will my SQUID logs show 1 MB of
data? It doesnt seem like it does.

Cheers,
M
