• It's important to know how to perform exception handling in Perl code. Exception handling is a general Perl technique; it's not mod_perl-specific. Further information is available in the documentation for the following modules:

  • Error.pm, by Graham Barr.

  • Exception::Class and Devel::StackTrace, by Dave Rolsky.

  • Try.pm, by Tony Olekshy, available at http://www.avrasoft.com/perl6/try6-ref5.txt.

  • There is also a great deal of information concerning error handling in the mod_perl online documentation (e.g., http://perl.apache.org/docs/general/perl_reference/perl_reference.html).

• Perl Module Mechanics: http://world.std.com/~swmcd/steven/perl/module_mechanics.html.

  This page describes the mechanics of creating, compiling, releasing, and maintaining Perl modules, which any mod_perl developer planning on sharing code with others will find useful.
