our $VERSION = '0.03';


=head1 SYNOPSIS

Uninets::Check::Modules::HTTP can check return status, response time and size of web resources.

sub run {
    my ($self, $action, @params) = @_;

    $self->$action(@params);
}

=head1 ACTIONS

=head2 status

Get the status code of a call to an URL.

    unicheck HTTP status --url example.com

    defined $status ? $self->_return($status, $headers, $format) : $self->_return(-1, 'Something went wrong', $format);
}

=head2 time

Get the delivery time of a web resource in milliseconds.
