With the upcoming release of Apache 2.0, the most popular web server on the Internet looks to extend its 60% marketshare with increased flexibility, portability, and performance.

Apache Today has a nice column that attempts to explain some of the new features and improvements in the forthcoming Apache 2.0 release.

"Perhaps the biggest change in Apache 2.0 is the Apache Portable Run-Time (APR). In

previous versions of Apache, portability for Apache was handled internally, which kept Apache

developers from doing what they really wanted, making the most popular web server. With

Apache 2.0, portability is handled by APR. APR is a project that is currently tied to Apache, but

should be spun off into its own project soon after the official 2.0 release. The goal of APR is to

provide a single C interface to platform- specific functions so that code can be written once and

compiled and run everywhere."
