Accelerating Apache farms through ad-HOC distributed scalable objects repository

We present HOC: a fast, scalable objects repository providing programmers with a general storage module. HOC may be used to implement DSMs as well as distributed cache subsystems. HOC is composed by a set of hot-pluggable cooperating processes that may sustain close to optimal network traffic rates. We designed an HOC-based Web cache that extends the Apache Web server and remarkably improves Apache farms performances with no modification to the Apache core code.
