"ApacheCon 2001 is advertised as the only Apache event to be fully supported by the Apache Software Foundation. Apache founders and leading contributors have designed the technical program consisting of 40 sessions with over 100+ hours of instruction."
"... This week's hot topic was whether or not the separation of HTTP code from the "core server" in Apache 2.0 should continue.

Currently though, the code is still tied to HTTP, and Ryan Bloom has been trying to change this."
