Your code worked fine for me, I can only see a problem if your running behind a VPN or gateway as previous stated. Always use strict
and warnings
, and here is an alternative way so you are not initializing a new Request object everytime you want to check for a valid link.
use strict;
use warnings;
use LWP::UserAgent;
sub check_url {
my ($url) = @_;
my $ua = LWP::UserAgent->new;
my $req = HTTP::Request->new(HEAD => $url);
my $res = $ua->request($req);
return $res->status_line if $res->is_error;
return "Success: $url";
}
