Apache Module mod_imagemap Description: Server-side imagemap processing Status: Base ModuleIdentifier: imagemap_module SourceFile: mod_imagemap.c Summary This module processes .map files, thereby replacing the functionality of the imagemap CGI program. Any directory or document type configured to use the handler imap-file (using either AddHandler or SetHandler) will be processed by this module. The following directive will activate files ending with .map as imagemap files: AddHandler imap-fi

Apache Module mod_ident Description: RFC 1413 ident lookups Status: Extension ModuleIdentifier: ident_module SourceFile: mod_ident.c Compatibility: Available in Apache 2.1 and later Summary This module queries an RFC 1413 compatible daemon on a remote host to look up the owner of a connection. IdentityCheck Directive Description: Enables logging of the RFC 1413 identity of the remote user Syntax: IdentityCheck On|Off Default: IdentityCheck Off Context: server config, virtual host, direct

Apache Module mod_http2 Description: Support for the HTTP/2 transport layer Status: Extension ModuleIdentifier: http2_module SourceFile: mod_http2.c Compatibility: Available in version 2.4.17 and later Summary This module provides HTTP/2 (RFC 7540) support for the Apache HTTP Server. This module relies on libnghttp2 to provide the core http/2 engine. Warning This module is experimental. Its behaviors, directives, and defaults are subject to more change from release to release relative to ot

Apache Module mod_heartmonitor Description: Centralized monitor for mod_heartbeat origin servers Status: Experimental ModuleIdentifier: heartmonitor_module SourceFile: mod_heartmonitor.c Compatibility: Available in Apache 2.3 and later Summary mod_heartmonitor listens for server status messages generated by mod_heartbeat enabled origin servers and makes their status available to mod_lbmethod_heartbeat. This allows ProxyPass to use the "heartbeat" lbmethod inside of ProxyPass. This module u

Apache Module mod_heartbeat Description: Sends messages with server status to frontend proxy Status: Experimental ModuleIdentifier: heartbeat_module SourceFile: mod_heartbeat Compatibility: Available in Apache 2.3 and later Summary mod_heartbeat sends multicast messages to a mod_heartmonitor listener that advertises the servers current connection count. Usually, mod_heartmonitor will be running on a proxy server with mod_lbmethod_heartbeat loaded, which allows ProxyPass to use the "heartbea

Apache Module mod_headers Description: Customization of HTTP request and response headers Status: Extension ModuleIdentifier: headers_module SourceFile: mod_headers.c Summary This module provides directives to control and modify HTTP request and response headers. Headers can be merged, replaced or removed. Order of Processing The directives provided by mod_headers can occur almost anywhere within the server configuration, and can be limited in scope by enclosing them in configuration sec

Apache Module mod_filter Description: Context-sensitive smart filter configuration module Status: Base ModuleIdentifier: filter_module SourceFile: mod_filter.c Compatibility: Version 2.1 and later Summary This module enables smart, context-sensitive configuration of output content filters. For example, apache can be configured to process different content-types through different filters, even when the content-type is not known in advance (e.g. in a proxy). mod_filter works by introducing ind

Apache Module mod_file_cache Description: Caches a static list of files in memory Status: Experimental ModuleIdentifier: file_cache_module SourceFile: mod_file_cache.c Summary This module should be used with care. You can easily create a broken site using mod_file_cache, so read this document carefully. Caching frequently requested files that change very infrequently is a technique for reducing server load. mod_file_cache provides two techniques for caching frequently requested static file

Apache Module mod_ext_filter Description: Pass the response body through an external program before delivery to the client Status: Extension ModuleIdentifier: ext_filter_module SourceFile: mod_ext_filter.c Summary mod_ext_filter presents a simple and familiar programming model for filters. With this module, a program which reads from stdin and writes to stdout (i.e., a Unix-style filter command) can be a filter for Apache. This filtering mechanism is much slower than using a filter which is

Apache Module mod_expires Description: Generation of Expires and Cache-Control HTTP headers according to user-specified criteria Status: Extension ModuleIdentifier: expires_module SourceFile: mod_expires.c Summary This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access. These HT
