Hi

I have

use WWW::Mechanize;
my $agent=WWW::Mechanize->new(autocheck => 1);
my ($url,$response,$content);
$url="http://www.example.com";
$agent->get($url); # main page
if (defined $agent) { whatever ...} else {print 'cannot connect'}

I get an error message if I cannot connect. I thought the if (defined
$agent) would catch this but it does not. Why?

Regards
John

Where did you get the idea the $agent object would become undef if the
get() method can't connect?
See section "Status Methods" in the documention of WWW::Mechanize for
how to check for errors.

Many thanks.

Got it at $agent->success() or $agent->status();
