(** Minimal implementation of an HTTP 1.0/1.1 client. Interface is similar to
 * Gerd Stoplmann's Http_client module. Implementation is simpler and doesn't
 * handle HTTP redirection, proxies, ecc. The only reason for the existence of
 * this module is for performances and incremental elaboration of response's
 * bodies *)

   * @param url an HTTP url
