Checks if WWW-Authenticate exists and contains a "Bearer" value (see rfc6750 section 3.1 for more details). If so, it refreshes the token in case the error code contains invalid_token. If there is no "Bearer" in WWW-Authenticate and the status code is HttpStatusCodes.STATUS_CODE_UNAUTHORIZED it refreshes the token. If the token refresh throws an I/O exception, this implementation will log the exception and return false.
