var httpStatusCodes = {
    // 1xx Informational
    // Request received, continuing process.[2]
    // This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.
    '100': 'Continue', //This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100-continue as a header in its initial request[2] and check if a 100 Continue status code is received in response be

 * - It instantiates only a single object
 * - Its safe – it keeps the reference to the singleton inside a variable, which
 *   lives inside a lexical closure and is not accessible by the outside world
 * - It allows you to initialize the singleton with some arguments. The module
 *   pattern, which wraps the singleton is not aware of the initialization
 *   arguments – it simply forwards the call with apply
 * - You can use the instanceof operator
