in reply to How do I get errors printing out to the browser?

First off, you need to understand that if a Perl script fails perl -c then the server is only going to issue an internal error to your browser. Sorry! That's it! End of story!

    Why do you say that? fatalsToBrowser will report errors to the browser whether the script compiles or not. It even reports line numbers and paths, which is a good reason to remove fatalsToBrowser in production code.

      Just to verify what jsprat is saying: 

      #!/usr/bin/perl -w

use CGI ':standard';
use CGI::Carp qw(fatalsToBrowser);

$i = 6; || $j = 7;

      chriso: Do you see the same problems with this simple script, or does it display the error in the browser as you expect?

      OK.... maybe it is a case of YMMV and depends on the server and its configuration. I was able to verify what you are saying as true on my test apache server at home.

      However, in my professional experience what I said in my reply is also true with a lot of servers and server configurations.
