For example, here is a web server which ignores the client's request
and always returns Goodbye, World:

<syntaxhighlight lang
This version works because reasonable http requests fit in a single tcp packet.
(And note that the server waits for one tcp packet before responding.)

with a queue size limit of 50 waiting requests imposed by default in the <code>ServerSocket</code> class (may be changed by adding a second positive integer argument to the <code>ServerSocket</code> constructor).

Various modules exist for using sockets, including the popular IO::Socket
which provides a simpler and more friendly OO interface for the socket layer.
Here is the solution using this module:
{{libheader|IO::Socket::INET}}
<
my $sock = new IO::Socket::INET ( LocalAddr => "127.0.0.1:8080",
Line 1,407 ⟶ 1,480:
"<html><head><title>Goodbye, world!</title></head><body>Goodbye, world!</body></html>\r\n";
close $client;
}</
Using Perl's glue power, provide a
with visitor counter via netcat:
<
open NC, "|-", qw(nc -l -p 8080 -q 1);
print NC "HTTP/1.0 200 OK\xd\xa",
"Content-type: text/plain; charset=utf-8\
"Goodbye, World! (hello, visitor No. $vn!)\
}</
Here's another solution using Plack (may be found on CPAN):
<
my $app = sub {
return [ 200,
Line 1,428 ⟶ 1,501:
my $runner = Plack::Runner->new;
$runner->parse_options('--host' => 'localhost', '--port' => 8080);
$runner->run($app);</
