We also assume that you know the basics of web server administration—if not with the Apache server itself, then with another Unix or Microsoft Windows-based web server.

A knowledge of the Perl programming language is definitely required! We use the Perl version of the Apache API to illustrate the central concepts of module design and implementation, and most of our example code is written in Perl as well. We chose to do it this way because we think there are more people who are comfortable developing web applications in Perl than in C or C++.

If you know Perl Version 4 but haven't gotten around to reading about the Version 5 features, now's the time to start learning about hash references, blessed objects, and method calls.
