The Apache/Perl Modules
Where Are The Modules Kept?
More Info


The Apache/Perl module list is here for the same reason as the main Perl module list, to change duplication of effort into cooperation and help to save the world! Apache/Perl modules are somewhat different from the many others found on CPAN. Most Perl modules are "building blocks", developers use them to build applications or even more building blocks. It just so happens that Apache/Perl modules are encapsulted inside a namespace and .pm file. However, this does not make them all building blocks, many are just like apache modules written in C, you install, edit the server configuration files and you're done. Before you start a new module, consider this: Apache/Perl modules are useless outside of mod_perl and Apache. Do your best to design such that your Apache::* module will make good use of the building blocks found on CPAN, putting together new building blocks where appropriate and simply glue them together with the Apache API, keeping the Apache::* modules very small.

These modules will also serve as good examples, showing you where modules can step in during a stage of a request with Perl*Handler callbacks. You'll also see how and when to use the Apache API methods.

Playing Your Part

Apache and Perl are world-wide collaborative efforts, naturally, the Apache/Perl integration project is the same.
You've started on the right foot simply by reading this document, thanks!
Please be sure you've read the main Perl module list, all that is said there is relevant here!

If you have any additions or changes for the list, please send them to the Apache/Perl mailing list or to me.

If you wish to share you module(s) the Perl way, by putting them on CPAN, send a request to me or to get set up with a PAUSE user id and directory.

HINT: For a nice set of template files try this:

% h2xs -AX -n Apache::YourPackageName

Where Are The Modules Kept?

Modules listed with the APML as is contact are part of the mod_perl distribution package. Other modules can be found on CPAN the modules/by-module/Apache/ directory. If they have not made it to CPAN yet, they might be found in the mod_perl contrib directory, which is also tar'd and distributed via CPAN in the modules/by-module/Apache/ directory. Otherwise, feel free to ask the contact author or the list how you can go about getting your hands on a copy.
