CGI::Carp was designed specifically for this. I use a configuration identical to yours and have not had problems with this technique. Perl CGI errors invariably end up in the error logs as desired (or in the browser for those cases where I specify fatalsToBrowser).

Is this just not working for you?

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
