### Multi destination replication

The replication design for multiple sites works in a similar manner as described above for two site scenario. However there are some
important exceptions.

Replication status on the source cluster will be marked as `COMPLETED` only after replication is completed on all targets. If one or more targets failed replication, the replication status is reflected as `PENDING`.

 *  Fix: When a network interceptor mutates a request, that change is now
    reflected in `Response.networkResponse()`.
 *  Fix: Badly-behaving caches now throw a checked exception instead of a
    `NullPointerException`.
 *  Fix: Better handling of uncaught exceptions in MockWebServer with HTTP/2.
