Serving Static Assets via Nginx

Concept

  • People talk about two servers: a web server (e.g. Nginx, Apache, etc.) and a app server (e.g. Language specific servers like Unicorn, Node.js, Tomcat, Http-Kit, etc.). There are exceptions where app servers not required at all (as web server itself provides preprocessors for handling), but let's not talk about now.
  • Web servers are really fast and supports lot of standard and commonly used MIME-type requests. Concept of serving a file is -- forming and sending a response of bytes of data and labeling it with requested MIME-type by a client (e.g. web browser).
  • Every response format (in layman's language, a file) is recognized by it's MIME-type, for e.g. a PNG image file has "image/png" MIME-type. JavaScript file has "text/javascript". HTML responses (or files) has "text/html". Plain text files have "text/plain".
  • Modern Browsers supports a lot of standard MIME-types. Images, videos, text files (XML, HTML, SVG, JS), and they better know how to visualize it. Browser also knows unrec
