In 2003, I wrote a series of articles on mod_perl 2.0 for perl.com, which I have exported as PDF documents and archived here.
- Filters in Apache 2.0 begins the series with an introduction to Apache 2.0's new output filter mechanism.
- Testing mod_perl 2.0 discusses how to use the powerful Apache-Test framework to test your mod_perl applications.
- Integrating mod_perl with Apache 2.1 Authentication shows how to leverage the new Apache 2.1 authentication provider mechanism and write Digest providers in Perl. It's very cool stuff.
You can find code from the articles in the code directory
- Apache-Clean-2.0 - code from both Filters in Apache 2.0 and Testing mod_perl 2.0
- Apache-Clean-1.0 - code from Testing mod_perl 2.0 that shows Apache-Test in use with mod_perl 1.x.
- Apache-AuthenHook-2.00_01 - code from Integrating mod_perl with Apache 2.1 Authentication
although all modules have been updated since then, and can be seen in their current version on CPAN
