Hi Mike, thanks for your reply.

The nice editors from perl.com fixed the download link after I mailed them.
The downloaded code clears up alot of things.
The wheel-id from POE::Wheel::SocketFactory is indeed the same throughout the whole program run.
Only the wheel-id in POE::Wheel:ReadWrite is different for each connection. This is the only wheel-id that needs to be stored (and destroyed).

I changed subroutines 'factory_success' and 'client_input' accordingly and it works now!

The code in the perl.com article and the code made available through the download link are different from each other which is a confusing for a POE newbie like me ;-)

sub factory_success {
  my $handle = $_[ARG0];


  my $wheel_id = POE::Wheel::ReadWrite->new( Handle      => $handle,
                                               Driver      => POE::Dri
+ver::SysRW->new(),
                                               Filter      => POE::Fil
+ter::SimpleQueryString->new(),
                                               InputEvent  => 'client_
+input',
                                             );

  $_[HEAP]->{clients}->{$wheel_id->ID} = $wheel_id;
}

sub client_input {
  my ($input, $wheel_id) = @_[ARG0, ARG1];

  use Data::Dumper;
  print Dumper $input;
  
  $_[HEAP]->{clients}->{$wheel_id}->put($input);
}
