ServerWatch: What's New and Improved in Apache 2.0 on Windows?
"This article outlines three major changes made to Apache that affect the 'fringes' (i.e., those platforms other than Unix), especially as they relate to the Windows platform. The first is a split between the server and the request processing logic into a Multiple Process Module, or MPM. The second change is the breaking out of platform-specific code into the Apache Portability Runtime library, or APR. The third, and biggest, Windows-NT-specific change is the introduction of Unicode, or utf-8 encoded filenames." This article by Covalent Technologies engineer and Apache Software Foundation member, William Rowe, Jr., outlines three major changes made to Apache that affect the platforms other than Unix, such as Multiple Process Modules, the Apache Portability Runtime library, and Unicode.
