Initially, Apache was the only viable open source alternative to the Netscape web server (nowadays known as iPlanet). It has since evolved to rival (and probably surpass) almost any other Unix based HTTP server in terms of functionality and speed. Since April 1996 Apache has been the most popular HTTP server on the Internet; in May 1999 it was running on 57% of all web servers. In May 2003 this percentage increased to 62%.
Apache is redistributed as part of various proprietary packages, e.g., the Oracle database or the IBM WebSphere application server. It is also supported in some way by Borland in the Kylix and Delphi development tools.
The Apache HTTP Server is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.
Apache has other powerful features included in a large set of modules, including mod_perl, an authentication module (.htaccess) as well as a web proxy module and an extremely useful URL rewriter (also known as a rewrite engine) called mod_rewrite. Apache logs can be analysed through a web browser using free scripts such as awstats.
