on this side of the planet (Australia), just about *all* service-providers
offer differentiated-billing baed on a volume-usage basis.
that includes Worldcom, Telstra, Optus (SingTel), connect.com.au (AAPT).
some of these differentiate themselves by using caching to provide faster
access and/or mitigate the latency overhead of simplex satellite.
this has been ongoing for many many many years now. please just accept
that HTTP caching is almost a necessity with the pricing models in use!

we're almost talking about the same thing here -- and this is my point! i
agree that is is important - hence why i've added a getsockopt() option to
provide octet counters from the ip+tcp level!

not at all. they're using it because it meets their requirements.

once again, i respectfully disagree. while there are numerous technologies
for accounting out there (e.g. netflow), they all break down when you have
things like HTTP Persistent connections which may share a single
[server-side] connection with multiple [client-side] connections.

you live in a country where the billing regeme is different.

(yes, i did take that comment as humerous before :-)).
if what i was proposing involved a new system-call then i agree that there
would be signficant pushback. what i have is a new getsockopt()
option. ie. in reality, no worse than getsockopt(..,TCP_INFO).
