Simple node http server

lesson-02

Simple node http server that reads index.html from file system

Building a full-fledged web framework is a lot of work:

• should support multiple formats and mime types (example only returns text/html)
• need to be more flexible about loading resources (example is hard-coded for index.html)
• should stream the response data (servers shouldn't buffer files into memory)
• doesn't parse url for query parameters
• doesn't do any caching, and doesn't set any client cache headers
