- Apache modules
Modules are bits of source code that can either be built into the 'httpd' binary or built separately as shared object files.
Shared object files are referred to as DSOs (Dynamically Shared Objects).
DSOs are loaded and unloaded from memory on demand.
- a module's status (apache docs) indicates how tightly bound into the Apache Web server the module is
- depending on it's status it may be necessary to recompile the server in order to gain access to a module and its functionality.
Possible status values:
a Multi-Processing Module. Unlike the other types of modules, Apache must have one and only one MPM in use at any time. This type of module is responsible for basic request handling and dispatching.
the module is compiled and loaded into the server by default and is therefore normally available unless you have taken steps to remove the module from your configuration.
the module is not normally compiled and loaded into the server. To enable the module and its functionality, you may need to change the server build configuration files and re-compile Apache.
the module is available as part of the Apache kit, but you are on your own if you try to use it. The module is being documented for completeness, and is not necessarily supported.
Modules which are not included with the base Apache distribution ("third-party modules") may use the "External" status. We are not responsible for, nor do we support such modules.
