SPEED-UP NOTE

If protocol level 1 is specified, the connect method tries to use the highest available protocol level. To do so, it queries the FreeDB to find out exaclty which level is supported. On HTTP connections this takes long. To speed up HTTP connections specify a higher proto_level -say 5 before connect() is called.

# Make connection through user agent
my $connection = LWP::UserAgent->new();
defined($connection) ||
    throw Error::Simple ("ERROR: InfoSys::FreeDB::Connection::HTTP::connect, Failed to instantiate an \'LWP::UserAgent\' object.");

# Set _connection_
$self->set__connection_($connection);

# Set proxy if required
if ( $self->get_proxy_host() ) {
    my $url =  'http://' . $self->get_proxy_host() . ':' .
                                                $self->get_proxy_port();
    $connection->proxy ('http', $url);
}

# Return if the protocol level is greater than 1
( $self->get_proto_level() > 1 ) &&
    return(undef);

# Check the stat
my $stat = $self->stat();

# Disconnect and throw exception if error
if ( $stat->is_error() ) {
    $self->set__connection_();
    throw Error::Simple("ERROR: InfoSys::FreeDB::Connection::HTTP::connect, handshake failed, stat returned an error.");
}

# Set the highest protocol
$self->set_proto_level( $stat->get_proto_max() );

# Return undef
return(undef);
