POE - portable multitasking and networking framework for Perl

A simple multitasking TCP Server

#!/usr/bin/perl

use warnings;
use strict;
use POE qw(Component::Server::TCP);

POE::Component::Server::TCP->new(
        Port => 12345,
        ClientConnected => sub {
            print "got a connection from $_[HEAP]{remote_ip}\n";
            $_[HEAP]{client}->put("Smile from the server.");

            $client_input =~ tr[a-zA-Z][A-Za-z];

POE::Kernel->run;

Timing the lifespan of a session

sub _start_handler {
    $_[HEAP]{ts_start} = time();
  }
  sub _stop_handler {
    my $time_elapsed = time() - $_[HEAP]{ts_start};
    print "Session ", $_[SESSION]->ID, " elapsed seconds: $elapsed\n";
  }
