      Bearing in mind that http is a send/receive protocol and that the client probably wants to know that a message did reach the server then this can be handled on the server in a slightly crude way. Override the handle() method in SOAP::Transport::HTTP::Daemon so that a response (200 OK) is sent back immediately, e.g. in your soapd.pl include the following:

      package SOAP::Transport::HTTP::Daemon;

      sub handle {
      my $self = shift->new;
      while (my $c = $self->accept) {
      while (my $r = $c->get_request) {
      undef $c;

      package main;

      Your client needs to then test for that particular return code

      $s->echo(SOAP::Data->name(text => $value));
      die 'dying ...', $s->transport->status
      unless $s->transport->status =~ m/200 OK/i;
      print "it seems to have worked!\n";

      If you really want to handle this on the client, then you can look at overriding the send_receive() method in SOAP::Transport:HTTP::Client so that it only sends. If you're really not worried about responses or even errors then you might want to use the tcp transport instead of http.

      I imagine Paul will have a cleaner way of handling this.
