NAME

       Net::Server::Fork - Net::Server personality

SYNOPSIS

	 use Net::Server::Fork;
	 @ISA = qw(Net::Server::Fork);

	 sub process_request {
	    #...code...
	 }

	 __PACKAGE__->run();

DESCRIPTION

       Please read the pod on Net::Server first.  This module is a personality, or extension, or sub class, of the Net::Server module.

       This personality binds to one or more ports and then waits for a client connection.  When a connection is received, the server forks a
       child.  The child handles the request and then closes.

       With the exception of parent/child signaling, this module will work (with basic functionality) on Win32 systems.

ARGUMENTS

       check_for_dead
	   Number of seconds to wait before looking for dead children.	This only takes place if the maximum number of child processes
	   (max_servers) has been reached.  Default is 60 seconds.

       max_servers
	   The maximum number of children to fork.  The server will not accept connections until there are free children. Default is 256 children.

       max_dequeue
	   The maximum number of dequeue processes to start.  If a value of zero or undef is given, no dequeue processes will be started.  The
	   number of running dequeue processes will be checked by the check_for_dead variable.

       check_for_dequeue
	   Seconds to wait before forking off a dequeue process.  It is intended to use the dequeue process to take care of items such as mail
	   queues.  If a value of undef is given, no dequeue processes will be started.

CONFIGURATION FILE

       See Net::Server.

PROCESS FLOW

       Process flow follows Net::Server until the post_accept phase.  At this point a child is forked.	The parent is immediately able to wait for
       another request.  The child handles the request and then exits.

HOOKS

       The Fork server has the following hooks in addition to the hooks provided by the Net::Server base class.  See Net::Server

       "$self->pre_accept_hook()"
	   This hook occurs just before the accept is called.

       "$self->pre_fork_hook()"
	   This hook occurs just after accept but before the fork.

       "$self->post_accept_hook()"
	   This hook occurs in the child after the accept and fork.

       "$self->run_dequeue()"
	   This hook only gets called in conjuction with the check_for_dequeue setting.

NAME

       Net::Server::MultiType - Net::Server personality

SYNOPSIS

	   use base qw(Net::Server::MultiType);

	   sub process_request {
	       #...code...
	   }

	   my @types = qw(PreFork Fork Single);

	   Net::Server::MultiType->run(server_type => @types);

DESCRIPTION

       Please read the pod on Net::Server first.  This module is a personality, or extension, or sub class, of the Net::Server module.

       This personality is intended to allow for easy use of multiple Net::Server personalities.  Given a list of server types,
       Net::Server::MultiType will require one at a time until it finds one that is installed on the system.  It then adds that package to its
       @ISA, thus inheriting the methods of that personality.

ARGUMENTS

       In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter.

	   Key		     Value	      Default
	   server_type	     'server_type'    'Single'

       server_type
	   May be called many times to build up an array or possible server_types.  At execution, Net::Server::MultiType will find the first
	   available one and then inherit the methods of that personality

CONFIGURATION FILE

       "Net::Server::MultiType" allows for the use of a configuration file to read in server parameters.  The format of this conf file is simple
       key value pairs.  Comments and white space are ignored.
