"Once the object is fetched by the client, Squid intercepts it and
stores the object for the other clients."
That sounds like heap LRU policy,
it is not fear to compare a squid out of the box with a solution that
has a tunning in parameters. Pesonally, i've develop an algorithm to
save you 30% of bandwith with some tunnings based on statistical
measures. So it is easy, you dont have to waste money.
