Nginx (pronounced “Engine-X”) is an open source Web server and a reverse proxy server with a strong focus on high concurrency, performance and low memory usage. It can deploy dynamic HTTP content on a network using FastCGI, SCGI handlers for scripts, uWSGI application servers or Phusion Passenger module, and can serve as a software load balancer.
I don’t use Nginx currently on any of my own web servers, but I do manage a customers images server which uses Nginx.

This post shows how to allow html files to be parsed successfully as PHP with Nginx + php-fpm.

I’ve recently set up a new server with PHP & Nginx using packages from dotdeb. The default upload_max_filesize and post_max_size for this setup with php-fpm is 2M. To adjust it, the Nginx config also needs a configuration change, otherwise you’re still stuck with a 2MB limit.
When migrating a mono application / web service running on one server to a new server I got an error telling me that the "Argument cannot be null" and "Parameter name: path". This post shows the full error message and the additional configuration options that needed to be set to fix it.
