Mostly by relying on TCP buffering and obeying the HTTP mandate that
client and server connections are independent.

Depends on several things...
* some of them configurable (read_ahead_gap, min/max buffer and message
sizes, collapsed_forwarding, pipeline_prefetch, etc),
* some of them outside Squid (TCP buffer and read/write block sizes, etc)
* cacheability / store involvement with the reply object


For what version of Squid?

NP: We are in the process of changing those particular parts of the code
for the Parser-NG project in 3.HEAD/trunk so the answer there differs
from the stables.
