 This example demonstrates the use of the {@link ResponseHandler} to simplify 
 the process of processing the HTTP response and releasing associated resources.

=end

client = DefaultHttpClient.new
httpget = HttpGet.new("http://www.google.com/")

puts "executing request " +httpget.getURI().toString()

response_handler = BasicResponseHandler.new()

response_body = client.execute(httpget, response_handler)

puts response_body

 When HttpClient instance is no longer needed, 
 shut down the connection manager to ensure
 immediate deallocation of all system resources

=end

client.getConnectionManager().shutdown();
