A redirect that uses 303 see other.

The redirect does NOT need a template and does NOT
render a text in the Http body by default.

If you wish to do so please
remove the {@link NoHttpBody} that is set as renderable of
the Result.

@param url
The url used as redirect target.
@return A nicely configured result with status code 303 and the url set
as Location header. Renders no Http body by default.
