| 软件简介： |
Lighttpd是一个德国人领导的开源软件，其根本的目的是提供一个专门针对高性能网站，安全、快速、兼容性好并且灵活的web server环境。具有非常低的内存开销，cpu占用率低，效能好，以及丰富的模块等特点。lighttpd是众多OpenSource轻量级的web server中较为优秀的一个。支持FastCGI, CGI, Auth, 输出压缩(output compress), URL重写, Alias等重要功能，而Apache之所以流行，很大程度也是因为功能丰富，在lighttpd上很多功能都有相应的实现了，这点对于apache的用户是非常重要的，因为迁移到lighttpd就必须面对这些问题。
Lighttpd 1.4.30 主要变化：
[mod_auth] Fix signedness error in http_auth (CVE-2011-4362)
ssl: disable client initiated renegotiations
ssl: support mitigating BEAST attack
fix connection stalls

支持PHP代码缓存，例如XCache,APC或eAccelarator
FastCGI负载均衡(one webserver distibutes request to multiple PHP-serversviaFastCGI)
Security, speed, compliance, and flexibility -- all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it s Open Source licensed under the revised BSD license.
lighttpd powers several popular Web 2.0 sites like YouTube, wikipedia and meebo. Its high speed io-infrastructure allows them to scale several times better with the same hardware than with alternative web-servers.
