Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.

Nginx may be configured to serve static web content or to act as a proxy server.

Nginx can be deployed to also serve dynamic content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger modules, and can serve as a software load balancer.

Nginx uses an asynchronous event-driven approach, rather than threads, to handle requests. Nginx's modular event-driven architecture can provide predictable performance under high loads.
