Server and client app demonstrating [Tornado][tornado]'s support of various 
HTTP methods.
Uses tornado.httpclient.AsyncHTTPClient.
One of the older demos.
Complexity: ★☆☆☆☆
Requirements
------------
Python (2 or 3), [Tornado][tornado], browser. Launch both server.py and 
client.py.
Effects
-------
- Visiting one of urls defined in client.py (`/get`, `/post`, etc) will 
  fetch and display response from server.py app.
- Even though server.py answers with some data in case of HEAD request, it 
  never reaches the client.py.
