  This is a basic test which allows you to setup a server and listen to it.
  
  For example, running:
  
  python integration/basic_server.py localhost 8040
  
  Sets up a server.
  
  Running curl against it generates the following reponse:
  
  curl 'http://localhost:8040/'
  <html><body><h1>ok</h1><br/>from 28330
  
  And in server output will print out the entire string (Lorem ipsum dolor etc.)
