Add new option ADD_NO_CACHE_HEADER on requests to registry server

README.md

@@ -110,6 +110,7 @@ Some env options are available for use this interface for **only one server**.
 - `READ_ONLY_REGISTRIES`: Desactivate dialog for remove and add new registries, available only when `SINGLE_REGISTRY=false`. (default: `false`).
 - `SHOW_CATALOG_NB_TAGS`: Show number of tags per images on catalog page. This will produce + nb images requests, not recommended on large registries. (default: `false`).
 - `HISTORY_CUSTOM_LABELS`: Expose custom labels in history page, custom labels will be processed like maintainer label.
+- `USE_CONTROL_CACHE_HEADER`: Use `Control-Cache` header and set to `no-store, no-cache`. This will avoid some issues on multi-arch images (see [#260](https://github.com/Joxit/docker-registry-ui/issues/260)). This option requires registry configuration: `Access-Control-Allow-Headers` with `Cache-Control`. (default: `false`).
 
 There are some examples with [docker-compose](https://docs.docker.com/compose/) and docker-registry-ui as proxy [here](https://github.com/Joxit/docker-registry-ui/tree/main/examples/ui-as-proxy/) or docker-registry-ui as standalone [here](https://github.com/Joxit/docker-registry-ui/tree/main/examples/ui-as-standalone/).
