lighttpd 1.4.40 发布高性能 Web 服务器

lighttpd 1.4.40 发布了。

Lighttpd 是一个德国人领导的开源Web服务器软件，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。
