=head1 NAME
Net::Server::MultiType - Net::Server personality
=head1 SYNOPSIS
use Net::Server::MultiType;
@ISA = qw(Net::Server::MultiType);
sub process_request {
#...code...
}
my @types = qw(PreFork Fork Single);
Net::Server::MultiType->run(server_type=>\@types);
=head1 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.
=head1 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'
=over 4
=item 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
