`
`nginx [engine x] is an HTTP and reverse proxy server, a mail proxy
`server, and a generic TCP/UDP proxy server, originally written by Igor
`Sysoev. For a long time, it has been running on many heavily loaded
`Russian sites including Yandex, Mail.Ru, VK, and Rambler. According
`to Netcraft, nginx served or proxied 23.06% busiest sites in March
`2021. Here are some of the success stories: Dropbox, Netflix,
`Wordpress.com, FastMail.FM.

`
`Basic HTTP server features
`
`• Serving static and index files, autoindexing; open file descriptor
`cache;
`• Accelerated reverse proxying with caching; load balancing and
`fault tolerance;
`• Accelerated support with caching of FastCGl, uwsgi, SCGI, and
`memcached servers; load balancing and fault tolerance;
`• Modular architecture. Filters include gzipping, byte ranges,
`chunked responses, XSLT, SSI, and image transformation filter.
`Multiple SSI inclusions within a single page can be processed in
`parallel if they are handled by proxied or FastCGl/uwsgi/SCGI
`servers;
`• SSL and TLS SNI support;
`• Support for HTTP/2 with weighted and dependency-based
`prioritization.
