I've been using SOAP::Lite, with very good results so far, to emulate some terminals that use SOAP to connect to a server.
I now need to add in heartbeat functionality.
I've found a problem with the server not always responding to heartbeats. I've raised this with the devs, but as the terminal I'm simulating copes with this, I need to be able to cope too. Thing is, SOAP Lite's "call" blocks for (or at least that's how I'm reading it) a response and the occasions when I get no response cause me to crash. Message gen code:

my $heartbeat = SOAP::Lite->new(proxy => $proxy);
    $heartbeat->default_ns('lws:Heartbeat');
    $heartbeat->autotype(0);
    $heartbeat->transport->timeout(1);

    $self->heartbeat($heartbeat);

    my $state = 1;

    my (@hbArgs) = (
        SOAP::Data->name( 'deviceName'   => $self->{id} ),
        SOAP::Data->name( 'username'     => $self->{userName} ),
        SOAP::Data->name( 'sessionId'    => $self->sessInfo->{sessionI
+d} ),
        SOAP::Data->name( 'state'        => $state ),
        SOAP::Data->name( 'taskId'       => $self->{taskId} ),
        SOAP::Data->name( 'location'     => ''),
    );

    my (@obj) = SOAP::Data->name(
        'obj' => \SOAP::Data->value( @hbArgs, ),
    );

    my (@message) = SOAP::Data->name(
        'message' => \SOAP::Data->value( @obj, ),
    );

    print "Let's try\n";
    $self->call( "heartbeat", "sendPulse", \@message);

    print "WE're back!!\n";

and my call:

sub call
{
    my ($self, $handle, $cmd, $params) = @_;
    

    if($cmd eq "sendPulse")
    {
        # Don't need to do anything with the heartbeat response
        $self->TOOLS::Print::sending("Sending heartbeat");
        $self->{$handle}->call( $cmd, @{$params} );
        return $self->{call};
    }

    $self->callResp($self->{$handle}->call( $cmd, @{$params} ));

    if($cmd ne "login")

Output:

SENDING HEARTBEAT
$proxy = 'http://128.0.100.135:14901';
Let's try
500 read timeout at /usr/users/stevew/Testing/Director/perl5/../lib/HHT.pm line 278
Line 278 being (from above):

        $self->{$handle}->call( $cmd, @{$params} );

Is there a way to send a SOAP message using SOAP::Lite and not expect a response?
