"to the client." may be redundant.

[Søren Gjesse, 2013/08/02 09:01:06]

Done.

+   *
+   * The [location] argument can be either a [Uri] or a [String]. If
+   * it is a [String] it is turned into a [Uri] using [Uri.parse].
+   *
+   * The redirect response will always have an absolute URI in the
+   * `Location` header. If the URI passed in [location] is relative it
+   * will be turned into an absolute URI by resolving it against the
+   * URI of the current request and the address and port of the
+   * server.
+   *
+   * By default the HTTP status code `302` is used for the redirect,
+   * but an alternative one can be specified using the [status]
+   * argument.
+   *
+   * This method will also call `close`, and the returned future is
+   * the furure returned by `close`.

I think it should be a named argument.

[Søren Gjesse, 2013/08/02 09:01:06]

Done.
