=head1 NAME

WWW::CNic - a web-based API for the CentralNic domain registry system.

=head1 SYNOPSIS

	use WWW::CNic;

	my @suffixlist = qw(uk.com us.com de.com eu.com);

	my $query = WWW::CNic->new(command => 'search', 'domain' => 'example');

	$query->set(suffixlist => \@suffixlist);

	my $response = $query->execute;

	if ($response->is_error) {
		printf("Error: %s\n", $response->error);

	} else {
		foreach my $suffix(@suffixlist) {
			if ($response->is_registered) {
				printf("Domain %s.%s is registered to %s\n", $domain, $suffix, $response->registrant($suffix));

			} else {
				printf("Domain %s.%s is available for registration\n", $domain, $suffix);

			}
		}
	}

=head1 DESCRIPTION

C<WWW::CNic> provides a powerful object-oriented Perl interface to the CentralNic Toolkit system.

The design of C<WWW::CNic> is inspired greatly by C<LWP>, which is a prerequisite. Essentially, making a transaction requires building a I<request> object, which is then executed and returns a I<response> object. While each transaction type (search, registration, modification...) requires a different set of data to be sent by the client, all the response objects have common properties, inherited from the C<WWW::CNic::Response> base class, with just a few extra methods for accessing specific information.

=head1 INSTALLATION

Installing C<WWW::CNic> is as simple as:

	cd /usr/src
	wget http://toolkit.centralnic.com/dist/WWW-CNic-x.xx.tar.gz
	tar zxvf WWW-CNic-x.xx.tar.gz
	cd WWW-CNic-x.xx
	perl Makefile.PL
	make
	make install

=head1 PREREQUISITES

=over

=item 1

C<LWP> - the WWW Library for Perl. This in turn requires C<libnet>, C<URI> and C<HTML::Parser>.

=item 2

An SSL toolkit (C<Crypt::SSLeay>, C<IO::Socket::SSL>) for doing HTTPS transactions.

=item 3

C<Digest::MD5> is needed for hashing passwords.

=back

=head1 USAGE

Consult L<WWW::CNic::Cookbook> for detailed information on using WWW::CNic.

=head1 CONSTRUCTOR

	my $query = WWW::CNic->new( [OPTIONS] );

The constructor for this class accepts the following options:

=over

=item 1

C<username> - only needed for doing domain registrations and modifications. This is the User ID of your Registrar Handle.

=item 2

C<password> - the password for your Registrar Handle.

=item 3

C<command> - required for every transaction. This is a scalar containing the command name. The list of allowed commands is always growing, you should consult the Toolkit website for a complete list.

=item 4

C<domain> - only needed for domain registrations, modifications and other commands that act upon domains.

=item 5

C<host> - allows you to use to a non-standard host. This is mainly useful for client debugging purposes.

=item 6

C<test> - when set to C<1>, this causes any domain registration and modification transactions to use the test database. Again, this is useful for testing and debugging.

=item 7

C<keep_alive> - by default, WWW::CNic will use C<LWP::ConnCache> to cache server connections. Setting C<keep_alive> to C<0> or C<undef> will turn this off.

=back

=head1 METHODS

	$query->set( NAME => VALUE );

This method allows you to set any number of parameters prior to executing the query. The specifics of what parameters are required for what type of transaction is explained in L<WWW::CNic::Cookbook>.

	my $response = $query->execute();

This method makes the transaction and returns an instance of a C<WWW::CNic::Response> child class.
