I think you are right, and since upload speeds are even slower that must

I am trying it right now, nice!

Thanks, I am giving it a try.
I'll start by following
http://wiki.squid-cache.org/ConfigExamples/Intercept/DebianWithRedirectorAndReporting
which seems similar to what i am trying to achive. If I am mistaken,
please let me know.
and also most of

May be I'll try that after basic http :)
