Nginx(engine x)是一个高性能的HTTP和反向代理服务器,也是一个IMAP/POP3/SMTP代理服务器. Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的,它已经在该站点运行超过两年半了.其特点是占有内存少，并发能力强，事实上Nginx 的并发能力确实在同类型的网页伺服器中表现较好。目前中国大陆使用Nginx网站用户有：新浪、网易、腾讯。Changes with nginx 0.8.48                                        03 Aug 2010

       Thanks to Christine McGonagle.

    *) Bugfix: the "proxy_pass", "fastcgi_pass", "uwsgi_pass", and
       "scgi_pass" directives were not inherited inside "limit_except"
       blocks.

    *) Bugfix: the "proxy_cache_min_uses", "fastcgi_cache_min_uses"
       "uwsgi_cache_min_uses", and "scgi_cache_min_uses" directives did not
