This a lot easier than you think ...

my $ua = LWP::UserAgent->new;
my $request = HTTP::Request->new('GET' => $url);
my $response = $ua->request($request)

if ($response->is_error) {
    ...
} else {
    ...
}

Alternatively, you could employ the is_success method for testing for successful retrieval of the passed URL. Furthermore, the actual numeric response code received can be returned with the code method. For further details on HTTP::Response methods, see the HTTP::Response man page.

 

perl -e 'print+unpack("N",pack("B32","00000000000000000000000111000011")),"\n"'
