Apache HTTP Server 2.0.35 GA

Apache has been the most popular web server on the Internet since 1996. The Apache project is an effort to develop and maintain an open-source HTTP server for various modern desktop and server operating systems, such as UNIX and Windows NT.

What's New:

On Unix systems with POSIX threads support, Apache can now run in a hybrid multiprocess, multithreaded mode. This improves scalability for many, but not all configurations
The build system has been rewritten from scratch to be based on autoconf and libtool
Apache now has some of the infrastructure in place to support serving multiple protocols. mod_echo has been written as an example
The API for modules has changed significantly for 2.0
On systems where IPv6 is supported by the underlying Apache Portable Runtime library, Apache gets IPv6 listening sockets by default
Apache modules may now be written as filters which act on the stream of content as it is delivered to or from the server
Many confusing directives have been simplified
