Nginx (pronounced “engine x”) is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Written by Igor Sysoev in 2005, Nginx now hosts between 1% and 4% of all domains worldwide. Although still in beta, Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption.

Basic HTTP features:

1. Handling of static files, index files, and autoindexing; open file descriptor cache;
2. Accelerated reverse proxying without caching; simple load balancing and fault tolerance;
3. Accelerated support without caching of remote FastCGI servers; simple load balancing and fault tolerance;
4. Modular architecture. Filters include gzipping, byte ranges, chunked responses, XSLT, and SSI. Multiple SSI inclusions within a single page can be processed in parallel if they are handled by FastCGI or proxied servers.
5. SSL and TLS SNI support.
