2、ache软件基金会的一个开放源码的网页伺服器，可以在大多数计算机操作系统中运行，由于其多平台和安全性被广泛使用，是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩展，将PerlPython等解释器编译到服务器中。Apache是世界使用排名第一的Web服务器软件。它可以运行在几乎所有广泛使用的计算机平台上。Apache源于NCSAhttpd服务器，经过多次修改，成为世界上最流行的Web服务器软件之一。Apache取自“a patchy server”的读音，意思是充满补丁的服务器，因为它是自由软件，所以不断有人来为它开发新的功能、新的特性、修改原来的缺陷。Apache的特点是
3、简单、速度快、性能稳定，并可做代理服务器来使用。本来它只用于小型或试验Internet网络，后来逐步扩充到各种Unix系统中，尤其对Linux的支持相当完美。Apache有多种产品，可以支持SSL技术，支持多个虚拟主机。Apache是以进程为基础的结构，进程要比线程消耗更多的系统开支，不太适合于多处理器环境，因此，在一个Apache Web站点扩容时，通常是增加服务器或扩充群集节点而不是增加处理器。到目前为止Apache仍然是世界上用的最多的Web服务器，市场占有率达60%左右。世界上很多著名的网站如A、Yahoo!、W3 Consortium、Financial Times等都是Apache
4、的产物，它的成功之处主要在于它的源代码开放、有一支开放的开发队伍、支持跨平台的应用（可以运行在几乎所有的Unix、 Windows、Linux系统平台上）以及它的可移植性等方面。Apache的诞生极富有戏剧性。当NCSA WWW服务器项目停顿后，那些使用NCSA WWW服务器的人们开始交换他们用于该服务器的补丁程序，他们也很快认识到成立管理这些补丁程序的论坛是必要的。就这样，诞生了Apache Group，后来这个团体在NCSA的基础上创建了Apache。Apache web服务器软件拥有以下特性： 支持最新的HTTP/1.1通信协议 拥有简单而强有力的基于文件的配置过程 支持通用网关接口 支
5、持基于IP和基于域名的虚拟主机 支持多种方式的HTTP认证 集成Perl处理模块 集成代理服务器模块 支持实时监视服务器状态和定制服务器日志 支持服务器端包含指令(SSI) 支持安全Socket层(SSL) 提供用户会话过程的跟踪 支持FastCGI 通过第三方模块可以支持Java Servlets 如果你准备选择Web服务器，毫无疑问Apache是你的最佳选择。本条目包含过多不是中文的内容，欢迎协助翻译。若已有相当内容译为中文，可迳自去除本模板。What IS the Apache HTTP Server Project?The Apache HTTP Server Project is a
6、 collaborative software development effort aimed at creating a robust, commercial-grade, featureful, and freely-available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicat

In addition, hundreds of users have contributed ideas, code, and documentation to the project. This file is intended to briefly describe the history of the Apache HTTP Server and re
8、cognize the many contributors.How Apache Came to BeIn February of 1995, the most popular server software on the Web was the public domain HTTP daemon developed by Rob McCool at the National Center for Supercomputing Applications, University of Illinois, Urbana-Champaign. However, development of that
9、 httpd had stalled after Rob left NCSA in mid-1994, and many webmasters had developed their own extensions and bug fixes that were in need of a common distribution. A small group of these webmasters, contacted via private e-mail, gathered together for the purpose of coordinating their changes (in th
10、e form of patches). Brian Behlendorf and Cliff Skolnick put together a mailing list, shared information space, and logins for the core developers on a machine in the California Bay Area, with bandwidth donated by HotWired. By the end of February, eight core contributors formed the foundation of the

12、nhancements we could find, tested the result on our own servers, and made the first official public release (0.6.2) of the Apache server in April 1995. By coincidence, NCSA restarted their own development during the same period, and Brandon Long and Beth Frank of the NCSA Server Development Team joi

During May-June 1995, while Rob Hartill and the rest of the group focused on implementing ne
14、w features for 0.7.x (like pre-forked child processes) and supporting the rapidly growing Apache user community, Robert Thau designed a new server architecture (code-named Shambhala) which included a modular structure and API for better extensibility, pool-based memory allocation, and an adaptive pr
15、e-forking process model. The group switched to this new server base in July and added the features from 0.7.x, resulting in Apache 0.8.8 (and its brethren) in August.After extensive beta testing, many ports to obscure platforms, a new set of documentation (by David Robinson), and the addition of many features in the form of our standard modules, Apache 1.0 was released on December 1, 1995.Less than a year after the group was formed, the Apache server passed NCSAs httpd as the #1 server on the Internet and according to the survey by Netcraft, it retains that position
