* The hash binds the response to the requested `(name, props, context, source)` tuple, so the
* server can reject requests whose URL hash does not match the supplied query/body. Use this
* from island clients if you need to ensure a hash stays in step with Nuxt's implementation.
*
* `props` may be passed either as the raw props object or as the JSON string that will be sent
* over the wire; the two produce the same hash when the round-trip is identity.
