Here's another suggestion - no fork, no signals.
Works on my Linux system - I don't have a Windows system to test on... 

#!/usr/bin/perl

use strict; # https://www.perlmonks.org/?node_id=11154445
use warnings;

use IO::Socket;
use IO::Select;

my $port = shift // 3333; # FIXME
my $listen = IO::Socket::INET->new( LocalPort => $port,
  Listen => 100, ReusePort => 1,) or die $&;
my $sel = IO::Select->new( $listen, *STDIN );
print "Hit <ENTER> to quit\n";
for( my $more = 1; $more; )
  {
  for my $handle ( $sel->can_read )
    {
    if( $handle eq *STDIN )
      {
      $more = 0;
      print "operator wants me to go away\n";
      }
    else
      {
      my $live_socket = $listen->accept;
      while( <$live_socket> )
        {
        # process stuff here
        print "GOT: $_";
        /^\r?\n\z/ and shutdown $live_socket, 1; # NOTE because testin
+g with GET
        }
      close $live_socket;
      }
    }
  }
