nginx is a free, lightweight, open-source, very powerful and
efficient web server and reverse proxy. It uses a scalable
event-driven (asynchronous) architecture in contrast to a threaded or
process-oriented approach to handling requests. This architecture uses
small, but more importantly, predictable amounts of memory under load.
This server can be used as standalone HTTP server and as a
reverse proxy server before some Apache or another big server to reduce
load to backend servers by many concurrent HTTP-sessions.
nginx now hosts nearly 7.50% (20.5M) of all domains worldwide.
It can also act as a POP3/IMAP mail proxy with SSL and TLS SNI support.
- Handling of static files, index files, and auto-indexing
- Accelerated reverse proxy with caching
- Simple load balancing
- 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
- 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
- 3xx-5xx error codes redirection
- The rewrite module
- Access control based on client IP address and HTTP Basic
- The PUT, DELETE, MKCOL, COPY and MOVE methods
- FLV streaming
- MP4 streaming
- Speed limitation
- Limitation of simultaneous connections or requests from one
- Embedded Perl
- Keepalive connections may be closed prematurely
- Support for keepalive connections to upstream servers
- Consolidation of multiple simultaneous requests to upstream
servers if caching is used
- Support for multiple request and connection limits used
- Reduced memory consumption in various edge cases like
handling of long-lived requests
