Apache modules included with IBM HTTP Server
This section provides information on Apache modules that are included with IBM® HTTP Server. The directives defined within the included Apache modules can be used to configure IBM HTTP Server.
Included Apache modules
Best practice: If you are using the mod_ibm_ldap
module for your LDAP configuration, consider migrating your mod_ibm_ldap directives to use the
mod_ldap module. The mod_ibm_ldap module is provided with this release of IBM HTTP Server for compatibility with previous releases, however, you must
migrate existing configurations to use the mod_authnz_ldap and mod_ldap modules to ensure future
support for your LDAP configuration.
The following Apache modules were changed or are no
longer included.- The mod_file_cache module is provided with this release of IBM HTTP Server for compatibility with previous releases, however, you must migrate existing configurations to use the mod_mem_cache module to ensure future support for your LDAP configuration. These modules provide equivalent function in the memory instead of on a disk.
- The mod_mime_magic module is provided with this release of IBM HTTP Server for compatibility with previous releases, but might not be available in a future release. No replacement will be provided for this module.
- The mod_proxy_ftp module is provided with this release of IBM HTTP Server for compatibility with previous releases, but might not be available in a future release. No replacement will be provided for this module.
- The mod_cern_meta module is not included. Instead use the mod_headers module.
- The mod_imap module was renamed to mod_imagemap. The LoadModule directive for the mod_imap module must be changed to refer to the new module name for an existing configuration file.
- You must set the EnableExceptionHook directive value to On for the mod_backtrace and mod_whatkilledus diagnostic modules.
- You may set the McacheMinObjectSize directive value to a minimum of 1 for the mod_mem_cache module. In previous releases, the minimum value was zero.
- The Compression_Level directive for the mod_deflate module was renamed to DeflateCompressionLevel.
- The configurations for the mod_ldap and the mod_auth_ldap modules have changed. See the following procedure about migrating from the mod_ldap and mod_auth_ldap module configurations.
- The Apache mod_example source is installed in the <ihsinst>/example_module directory.
- The AddOutputFilterByType directive now applies to proxy requests.
- Directory listings created by the mod_autoindex module now have a default character set which can be modified using the IndexOptions directive. If you rely on browser detection of character sets for correct display of directory listings, you might need to specify the correct character set using the IndexOptions directive.
- The mod_proxy_balancer and mod_proxy_ajp modules are not supported components of IBM HTTP Server. These modules are exclusively provided for, and
supported by the following IBM products that include the IBM HTTP Server as part of their package:
- WebSphere Community Edition uses both the mod_proxy_balancer and mod_proxy_ajp modules. Certain support agreements are required for these modules.
- WebSphere Commerce uses the mod_proxy_balancer module in direct support of the Social Commerce functionality.
Where applicable, these modules are distributed with IBM HTTP Server.
