Hello Monks,

I wrote a short program which needed to occasionally download Wikipedia articles. To my frustration the pages were not being downloaded. Luckily, I stumbled upon LWP::Simple::get($url) does not work for some urls, which basically states the default user-agent is blocked. After altering that my program worked like a charm.

But now my question is, how can I programmatically determine errors like this from LWP? It appears nothing is stored in $! after the failed get attempt. Does LWP have its own error variable? It would be nice for a program like the following to relay the error information to the user. 

use warnings;
use strict;
use LWP::Simple;

my @urls = (
    'http://www.google.es/',
    'http://www.perlmonks.org/',
    'http://es.wikipedia.org/',
);

foreach my $url (@urls) {
    my $content = get $url;
    $url =~ /\.(.*)\./;
    if ($content) {
        say "Received response from $1";
    } else {
        say "No response from $1, error ($!)";
    }
}
