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

Hello everyone --

I am currently proxying all traffic from the client through SQUID. I
am trying to measure the amount of bandwidth used by the client. The
client is connecting to Gmail.com via HTTPS.

I see the connections to Gmail in the access.log as such:

1239680667.335 216115 172.19.240.27 TCP_MISS/200 2964 CONNECT
mail.google.com:443 - DIRECT/74.125.155.18 -

but it doesnt seem like all client requests  show up in the log. I am
running Firebug 1.3.1 in the client and I see many GET and POST
requests from the client to Google that don't show up in the
access.log.

Can I use SQUID for this function? Ie measure bandwidth for HTTPS
traffic for 1 and eventually multiple users? Is it accurate?

My setup.
