This is what others mentioned:
use LWP::UserAgent;
use HTTP::Request;
my $agent = new LWP::UserAgent();
while (<DATA>) {
chomp;
my $res = $agent->request(new HTTP::Request(GET => $_));
if ($res->is_success) {
print $res->content;
} else {
print "failed to get $_\n";
}
}

Well, there is no harm to play with socket, so here you are (pay attention to that comment I made in the following demo):
use IO::Socket;
while (<DATA>) {
chomp;
print "try to connect to host $_ ...\n";
$sock = new IO::Socket::INET(PeerAddr => $_,
PeerPort => 80,
Proto => 'tcp',
Timeout => 10
);
if (!defined($sock)) {
print "failed to connect to host $_\n";
next;
} else {
print "connected to host $_\n";
}
print $sock "GET http://$_ HTTP/1.1\r\n" .
"Host: $_\r\n\r\n";
print $_ while (<$sock>); #this will fail to end, if peer does not
+ close the connection
close($sock);
}
