Apache is an open source HTTP server. It comprises a small core for HTTP request/response processing and Multi-Processing Modules (MPM) which dispatches data processing to threads and/or processes. Many additional modules are available to extend its 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[1]
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[2]
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 filesystem and for the requests to be redirected entirely[3]
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[4]
mod_aspdotnet 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[5]
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[6]
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 module replaces the authentication frontend of several older modules.[7]
mod_auth_db Versions 1.1-1.3 Stable Extension Apache Software Foundation Apache License, Version 2.0 Provides user authentication using Berkeley DB files.
mod_auth_dbm Versions older than 2.1 Stable Extension Apache Software Foundation Apache License, Version 2.0 This module provides for HTTP Basic Authentication, where the usernames and passwords are stored in DBM type database files. It is an alternative to the plain text password files provided by mod_auth.
mod_auth_digest Versions 1.3.8 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 Authenticates users via HTTP Digest Authentication utilizing MD5 encryption. 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.[8]
mod_auth_kerb
mod_auth_ldap Versions 2.0.41-2.1 Experimental Extension Apache Software Foundation Apache License, Version 2.0 Allows HTTP Basic Authentication by checking against an LDAP directory. The authentication mechanism of checking against an LDAP directory is provided via mod_authnz_ldap in Apache versions 2.1 and later.
mod_auth_oid Version 2.2 Third-party module Pascal Buchbinder GNU General Public License, Version 2 Allows an Apache server to act as an OpenID "Relying Party"[9]
mod_authn_alias Version 2.1 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 This module allows extended authentication providers to be created within the configuration file and assigned an alias name. The alias providers can then be referenced through the directives AuthBasicProvider or AuthDigestProvider in the same way as a base authentication provider.
mod_authn_anon Version 2.1 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 Acts as an authentication provider to other modules, like mod_auth_basic and mod_auth_digest, users are authenticated by using a special user id of "anonymous" and providing their email as the password.[10]
mod_authn_dbd Version 2.1 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 This module provides authentication front-ends such as mod_auth_digest and mod_auth_basic to authenticate users by looking up users in SQL tables. Similar functionality is provided by, for example, mod_authn_file.
mod_authn_dbm Version 2.1 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 This module provides authentication front-ends such as mod_auth_digest and mod_auth_basic to authenticate users by looking up users in dbm password files. 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 configured an authentication module like mod_auth_basic. 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.[11]
mod_authnz_external
mod_authnz_ldap Version 2.1 and newer Stable Extension Apache Software Foundation Apache License, Version 2.0 Acts as an authentication provider to other modules and checks authentication against an LDAP directory

mod_bonjour
mod_bw The httpd web server doesn't really have a way to control how much resources a given virtual host can have/ a user can request. This module should be able to limit access to certain areas of the website and to limit malicious users.
mod_bwlimited mod_bwlimited is a CPanel module that allows limiting and monitoring of bandwidth and connection speed etc. It allows CPanel to give very accurate reports of bandwidth usage on HTTP, HTTPS, FTP, SMTP and a few other services as well as limiting bandwidth usage and connection speed. The module is only available on servers running CPanel and isn't available anywhere else
