+This API replaces the current backend server settings with the

+acceptable.  The request body must be nghttpx configuration file

 Currently, only :option:`backend <--backend>` option is parsed, the
 others are simply ignored.  The semantics of this API is replace the
 current backend with the backend options in request body.  Describe
