	This is the resource agent for the Apache Web server.
	This resource agent operates both version 1.x and version 2.x Apache
	servers.

	The start operation ends with a loop in which monitor is
	repeatedly called to make sure that the server started and that
	it is operational. Hence, if the monitor operation does not
	succeed within the start operation timeout, the apache resource
	will end with an error status.

	The monitor operation by default loads the server status page
	which depends on the mod_status module and the corresponding
	configuration file (usually /etc/apache2/mod_status.conf).
	Make sure that the server status page works and that the access
	is allowed only from localhost (address 127.0.0.1).
	See the statusurl and testregex attributes for more details.
