nginx- Lightweight, high performance web server/reverse proxy and e-mail (IMAP/POP3) proxy

Nginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Igor Sysoev started development of Nginx in 2002, with the first public release in 2004. Nginx now hosts nearly 6.55% (13.5M) of all domains worldwide.

Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

Nginx is one of a handful of servers written to address the C10K problem. Unlike traditional servers,Nginx doesn’t rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but more importantly, predictable amounts of memory under load.

Even if you don’t expect to handle thousands of simultaneous requests, you can still benefit from Nginx’s high-performance and small memory footprint. Nginx scales in all directions: from the smallest VPS all the way up to clusters of servers. Nginx powers several high-visibility sites, such  as WordPress , Hulu, Github, Ohloh, SourceForge andTorrentReactor.

Basic HTTP features

• Serving static and index files, and autoindexing; open file descriptor cache;
• Accelerated reverse proxying with caching; simple load balancing and fault tolerance;
• Accelerated support with caching of remote FastCGI servers; simple load balancing and fault tolerance;
• Modular architecture. Filters include gzipping, byte ranges, chunked responses, XSLT, SSI, and image resizing filter. Multiple SSI inclusions within a single page can be processed in parallel if they are handled by FastCGI or proxied servers.
• SSL and TLS SNI support.

Other HTTP features

• Name-based and IP-based virtual servers;
• Keep-alive and pipelined connections support;
• Flexible configuration;
• Reconfiguration and online upgrade without interruption of the client processing;
• Access log formats, bufferred log writing, and quick log rotation;
• 3xx-5xx error codes redirection;
• The rewrite module;
• Access control based on client IP address and HTTP Basic authentication;
• The PUT, DELETE, MKCOL, COPY and MOVE methods;
• FLV streaming;
• Speed limitation;
• Limitation of simultaneous connections or requests from one address.
• Embedded perl.

Mail proxy server features

• User redirection to IMAP/POP3 backend using an external HTTP authentication server;
• User authentication using an external HTTP authentication server and connection redirection to internal SMTP backend;
• Authentication methods:
  • POP3: USER/PASS, APOP, AUTH LOGIN/PLAIN/CRAM-MD5;
  • IMAP: LOGIN, AUTH LOGIN/PLAIN/CRAM-MD5;
  • SMTP: AUTH LOGIN/PLAIN/CRAM-MD5;
• SSL support;
• STARTTLS and STLS support.
