List of Apache modules
Appearance
In computing, the Apache HTTP Server, an open-source HTTP server, comprises a small core for HTTP request/response processing and for Multi-Processing Modules (MPM) which dispatches data processing to threads and/or processes. Many additional modules (or "mods"[1] ) are available to extend the core functionality for special purposes.
The following is a list of all the first- and third-party modules available for the Apache web server:
Name | Compatibility | Status | Developer(s) | License | Description |
---|---|---|---|---|---|
mod_access | Versions older than 2.1 | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Provides access control based on the client and the client's request[2] |
mod_actions | Versions 1.1 and later | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Provides CGI ability based on request method and media type[3] |
mod_alias | Versions 1.1 and later | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Allows for client requests to be mapped to different parts of a server's file system and for the requests to be redirected entirely[4] |
mod_asis | Versions 1.3 and later | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Allows for the use of files that contain their own HTTP headers[5] |
mod_aspdotnet | Apache License, Version 2.0 | No longer under the Apache Software Foundation umbrella. Development has been resumed by the original authors at its new home, the mod-aspdotnet SourceForge project. | |||
mod_auth | Versions older than 2.1 | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Authenticates users via Basic access authentication by checking against plaintext password and group files. In Apache 2.1 and later, this plaintext authentication is enabled by mod_authn_file instead.[6] |
mod_auth_anon | Versions 1.1-2.1 | Stable Extension | Apache Software Foundation | Apache License, Version 2.0 | Allows authentication with a special user id of 'anonymous' and an email address as the password. As an authentication mechanism, this was replaced by mod_authn_anon.[7] |
mod_auth_basic | Versions 2.1 and newer | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Authenticates users via HTTP Basic Authentication, the backend mechanism for verifying user authentication is left to configurable providers, usually other Apache modules.

This is more secure than HTTP Basic Authentication provided by other modules. As of Apache 2.1, this module acts as a front-end to authentication providers who verify the actual login.[9] |
mod_auth_kerb | Both 1.x and 2.x series of Apache are supported | Masarykova universita | MIT_License | Using the Basic Auth mechanism, it retrieves a username/password pair from the browser and checks them against a Kerberos server | |

Similar functionality is provided by mod_authn_file. |
mod_authn_default | Version 2.1 and newer | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | This module is designed to be the fallback module, if you don't have an authentication module like mod_auth_basic configured. It simply rejects any credentials supplied by the user. |
mod_authn_file | Version 2.1 and newer | Included by Default | Apache Software Foundation | Apache License, Version 2.0 | Acts as an authentication provider to other modules, like mod_auth_basic and mod_auth_digest, by checking users against plaintext password files.[12] |
