- <p>This document describes changes to the Apache HTTPD API from
- version 2.2 to 2.4, that may be of interest to module/application
- developers and core hacks. At the time of writing, the 2.4 API
- is not finalised, and this document may serve to highlight
- points that call for further review.</p>
- <p>API changes fall into two categories: APIs that are altogether new,
- and existing APIs that are expanded or changed. The latter are
- further divided into those where all changes are back-compatible
- (so existing modules can ignore them), and those that might
- require attention by maintainers. As with the transition from
- HTTPD 2.0 to 2.2, existing modules and applications will require
- recompiling and may call for some attention, but most should not
- require any substantial updating (although some may be able to
- take advantage of API changes to offer significant improvements).</p>
- <p>For the purpose of this document, the API is split according
- to the public header files. These headers are themselves the
- reference documentation, and can be used to generate a browsable
- HTML reference with <code>make docs</code>.</p>
