Avoiding repeated config downloads

The app downloads a large config JSON on every launch even though it rarely changes. Which HTTP feature saves the most data?

A.Send If-None-Match with the stored ETag; the server replies 304 Not Modified with no body when nothing changedB.Use POST instead of GET for the requestC.Add a random query parameter to every request, so proxies and the OS cache store a separate copy and serve it faster next timeD.Turn off gzip compression
