mod_perl

Apache´s mod_perl is a powerful integration of the Perl programming language with the Apache HTTP server. It embeds a persistent Perl interpreter directly into the web server, enabling high-performance execution of Perl scripts and advanced web application capabilities. mod_perl transforms traditional CGI scripting into a robust, scalable, and efficient development environment, allowing developers to harness the full power of Apache and Perl for dynamic content generation, server customization, and application frameworks.

Features

• Persistent Perl interpreter embedded in Apache
• Full support for Apache 1.3 (mp1) and Apache 2.x (mp2) branches
• Accelerated execution of existing CGI scripts via Apache::Registry
• Ability to write custom Apache modules in Perl
• Access to all phases of the HTTP request cycle
• Perl-based configuration within httpd.conf
• Support for third-party modules and templating systems
• Compatibility with CPAN modules for extended functionality
• Built-in support for session management, authentication, and logging
• Application frameworks built on mod_perl infrastructure

Capabilities

• Dramatically improves performance by eliminating external interpreter startup
