HTTP is stateless, which simply means that each request or response maintains no information on previous requests or responses. Facilitating this sort of rapid-pattern network communication is the sort of I/O that Node is designed to excel at. While Node represents a much more interesting technology stack overall, it does help engineers in creating networked protocol servers. In this section, we will move through a general overview of how to set up a basic HTTP server and then into a few more specialized uses of the protocol.

var http = require('http');
