Chapter 19. Apache Modules
Modules are a key part of Apache. They provide much of the functionality administrators expect in a modern web server, including user tracking, CGI scripting, and authentication. However, we should warn you up front that not all the modules presented here are compiled by default into the Apache server; this can be configured by the administrator when the distribution is first compiled.
Table 19.1 describes the standard Apache modules.
