in thread Checking for undef after performing get()

Sure; I'd do something like:
my $doc = get(...); warn "get() failed" unless $doc;
I'm assuming that the page actually has content here. If it's an empty string, the test should be
... unless defined($doc);
The documenation in LWP::Simple does suggest using LWP::UserAgent if you need more information about the return code. Just a thought.

    Yes, LWP::UserAgent was the ticket. This was the ideal solution that I was seeking:
    my $ua = LWP::UserAgent->new; my $response = $ua->get($url); if ($response->is_success){ (good things happen) } else { my $failmsg= ($response->status_line); (print the $failmsg) return; }
    BUT, for this to work, the web based script, after being triggered by the get(), must return some response that is part of the HTTP protocol. I added this line to the top of the web based script:
    print "Content-type: text/html\n\n";
    Otherwise you receive a 500 Internal Server Error. Thanks again for the help!
