nginx [engine x] is an HTTP and reverse proxy server,
|
||
a mail proxy server,
|
||
and a generic TCP/UDP proxy server,
|
||
originally written by <a href="http://sysoev.ru/en/">Igor Sysoev</a>.
|
||
For a long time, it has been running
|
||
on many heavily loaded Russian sites including
|
||
<a href="http://www.yandex.ru">Yandex</a>,
|
||
<a href="http://mail.ru">Mail.Ru</a>,
|
||
<a href="http://vk.com">VK</a>, and
|
||
<a href="http://www.rambler.ru">Rambler</a>.
|
||
According to Netcraft, nginx served or proxied
|
||
<a href="https://news.netcraft.com/archives/2022/04/27/april-2022-web-server-survey.html">21.79%
|
||
busiest sites in April 2022</a>.
|
||
Here are some of the success stories:
