     *
     * - Protocol version
     * - HTTP method
     * - URI
     * - Headers
     * - Message body
     *

     *
     * - The values represented in $_SERVER.
     * - Any cookies provided (generally via $_COOKIE)
     * - Query string arguments (generally via $_GET, or as parsed via parse_str())
     * - Upload files, if any (as represented by $_FILES)
     * - Deserialized body parameters (generally from $_POST)

     * $_SERVER values MUST be treated as immutable, as they represent application
     * state at the time of request; as such, no methods are provided to allow
     * modification of those values. The other values provide such methods, as they
     * can be restored from $_SERVER or the request body, and may need treatment
     * during the application (e.g., body parameters may be deserialized based on
     * content type).

     * request to derive and match additional parameters (e.g., via URI path
     * matching, decrypting cookie values, deserializing non-form-encoded body
     * content, matching authorization headers to users, etc). These parameters
     * are stored in an "attributes" property.
     *
