Apache Proxy CRCsync

School Servers deployed with limited bandwidth would benefit significantly from a modern HTTP proxy in the spirit of Andrew Tridgell's rproxy.

rproxy codebase is now a bit dated, and its reliance on the rsync protocol is problematic, as the rsync protocol is encumbered by software patents. To resolve this Rusty Russell has been working on a new implementation based on a rolling CRC algorythm, called crcsync, and there are efforts underway to integrate into the appropriate modules of Apache 2.2.x, as Apache is an excellent and modular http proxy.
