squid : Optimising Web Delivery - IP Cache API

squid : Optimising Web Delivery

Detailed Description
The IP cache is a built-in component of squid providing Hostname to IP-Number translation functionality and managing the involved data-structures. Efficiency concerns require mechanisms that allow non-blocking access to these mappings. The IP cache usually doesn't block on a request except for special cases where this is desired.
