nginx（发音同engine x）是一款由俄罗斯程序设计师Igor Sysoev所开发轻量级的网页服务器、反向代理服务器以及电子邮件（IMAP/POP3）代理服务器。起初是供俄国大型的入口网站及搜寻引擎 Rambler（俄文：Рамблер）使用。此软件BSD-like协议下发行，可以在UNIX、GNU/Linux、BSD、Mac OS X、Solaris，以及Microsoft Windows等操作系统中运行。

Changes with nginx 0.8.46 19 Jul 2010 *)
Change: now the "proxy_no_cache", "fastcgi_no_cache", "uwsgi_no_cache", and "sÓgi_no_cache" directives affect on a cached response saving only.
*) Feature: the "proxy_cache_bypass", "fastcgi_cache_bypass", "uwsgi_cache_bypass", and "sÓgi_cache_bypass" directives.
*) Bugfix: nginx did not free memory in cache keys zones if there was an error during working with backend: the memory was freed only after inactivity time or on memory low condition.

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 0.8.45                                        13 Jul 2010

*) Feature: ngx_http_xslt_filter improvements.

parameter.
