The mod_proxy module was separated from the Apache 2.0 tree in February this year, to allow development of
the core server to continue independently of the proxy, and vice versa. Since then, the mod_proxy team has
made significant changes to bring the code up to date, and make it use the new Apache 2.0 module interface.
Now that development has stabilised, the group decided to bring the module back into the standard
distribution so it can gain more testing."
