| |
| <DL> |
| <DT><STRONG>Unix Threading</STRONG> |
| <DD>On Unix systems with POSIX threads support, Apache can now run in a |
| hybrid multiprocess, multithreaded mode. This should improve |
| scalability. |
| |
| <DT><STRONG>New Build System</STRONG> |
| <DD>The build system has been rewritten from scratch to be based on |
| autoconf and libtool. This makes Apache's configuration system more |
| similar to that of other packages. |
| |
| <DT><STRONG>Multiprotocol Support</STRONG> |
| <DD>Apache now has some of the infrastructure in place to support serving |
| multiple protocols. mod_echo has been written as an example. |
| |
| <DT><STRONG>Better support for non-Unix platforms</STRONG> |
| <DD>Apache 2.0 is faster and more stable on non-Unix platforms such as |
| BeOS, OS/2, and Windows. With the introduction of platform-specific |
| multiprocessing modules (MPM) and the Apache Portable Runtime (APR), |
| these platforms are now implemented in their native API, avoiding the |
| often buggy and poorly performing POSIX-emulation layers. |
| <DD>A list of the MPM's currently available is <a href="mpm.html">here</a>. |
| |
| <DT><STRONG>New Apache API</STRONG> |
| <DD>The API for modules has changed significantly for 2.0. Many of the |
| module-ordering problems from 1.3 should be gone. 2.0 does much of |
| this automatically, and module ordering is now done per-hook to |
| allow more flexibility. Also, new calls have been added that provide |
| additional module capabilities without patching the core Apache server. |

| <dl> |
| |
| <dt><strong>mod_auth_db</strong> |
| <dd>Now supports Berkely DB 3.0 |
| |
| <dt><strong>mod_auth_digest</strong> |
| <dd>Includes additional support for session caching across processes |
| using shared memory. |
| |
| <dt><strong>mod_charset_lite</strong> <dd>New module in Apache 2.0. |
| This experimental module allows for character set translation |
| or recoding. |
| |
| <dt><strong>mod_dav</strong> |
| <dd>New module in Apache 2.0. This module implements the |
| HTTP Distributed Authoring and Versioning (DAV) specification for |
| posting and maintaining web content. |
| |
| <dt><strong>mod_file_cache</strong> |
| <dd>New module in Apache 2.0. This module includes the functionality |
| of mod_mmap_static in Apache 1.3, plus adds further caching abilities. |
