in reply to www::mechanize - how to prevent it dying?

See the autocheck parameter, which turns all HTTP errors into fatal errors. When you turn autocheck off, you will need to do all error checking yourself.

my $mech = WWW::Mechanize->new( autocheck => 0 ); my $res = $mech->get('does.notexist.example'); $res->is_success or print "Uhoh\n";

Alternatively, use eval to trap fatal errors when making the original connection.

my $mech = WWW::Mechanize->new(); my $connected = eval { $mech->get('does.notexist.example'); 1 }; if (! $connected) { print "Uhoh\n"; };

Also see Try::Tiny to reduce the exception-dance to one less step (I haven't used it myself):

use Try::Tiny; my $mech = WWW::Mechanize->new(); try { $mech->get('does.notexist.example'); } catch { print "Uhoh: $_\n"; };

    This was a great answer, thank you. I have switched off autocheck. But then I realised that I was already doing a check after each $mech->get() by testing $mech->status. Is testing $mech->status adequate or does checking $res->is_success do something different or better?
