Thanks for the tip, but it seams that I am always having the same
results depending on the location of the origin server. I would agree
with you if the transfer rate changes in one of the cases, but the
problem is that a cached file is "always" transferred with a fixed
download rate (10 to 12 kbps if the origine server is local (on the
same network with squid server), and 4 to 5 kbps if not).
Can you please elaborate?
