Apache Multiprocessing

From Apache 2.0, you can choose the way that Apache handles simultaneos requests. This is done by chosing a Multiprocessing Module (MPM).

The MPM is chosen at configuration time, before compilation.

Which MPM to choose, depends on how you want your server to perform.

UNIX's default method is prefork, which is simalar to Apache 1.3's multiprocessing method.
