Apache 2 Pocket Reference

Preface

Apache is a powerful web server designed with a modular architecture to be both efficient and portable. It is extremely flexible, offering the ability for a single server to support multiple websites as virtual hosts and to act as a web proxy. Apache includes standard modules for caching, to support SSL/TLS connections, various authentication and authorization mechanisms, and a filtering system. There are many addon modules that extend Apache’s functionality providing features, such as templating engines, embedded interpreters for many scripting languages, and HTTP interfaces to systems such as the Subversion version control system.

This pocket reference summarizes Apache’s command-line options and the configuration directives for the modules in the standard distribution. It covers Apache version 2.2.9, but most information is applicable to any version of Apache 2. For comprehensive information, the scale of which is beyond the scope of a small guide such as this, the Apache documentation website (http://httpd.apache.org/docs/) should be your next point of referral.
