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

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; }` [download] 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";` [download] Otherwise you receive a 500 Internal Server Error. Thanks again for the help!
