A client (web browser) makes a connection to the server, thus using up
one Prefork_MPM child process or one Worker_MPM worker thread.

The client then issues a GET/POST/HEAD request and waits for the
response. The client may be permitted to make more than one
GET/POST/HEAD request without disconnecting, if KeepAlive is turned on,
otherwise the connection is closed, releasing the server resources to be
reused for another client (assuming the child process/thread isn't
reaped at that time).

Mark.
