IBM HTTP Server vs. Apache HTTP Server

IBM HTTP Server is based on Apache HTTP Server 2.4, with additional fixes. For behaviors affected by changes in Apache HTTP Server 2.4.12 and later, refer to the bundled copy of the Apache HTTP Server manual which will describe these changes, where applicable, in terms of IBM HTTP Server maintenance levels. See related reference: Apache modules (containing directives) supported by IBM HTTP Server for more information.

The Apache Web server can be built with many different capabilities and configuration options. IBM HTTP Server includes a set of features from the available options. For information about Apache Web server features supported in IBM HTTP Server, see the information center topics about Apache modules (containing directives), programs, Apache Portable Runtime (APR) and APR-util libraries, and Multi-processing module (MPM) and addressing modes.
