file doesn't seem uploaded in resource panel due to browser cache

in some browser scenario when you upload a file in resource panel the file isn't added to the list of available resources, this seems related to the fact that the response to the ajax request managing the list of available resources is cached by the browser. can we optimise the cache header, or add a random identifier to each request?

No file or test is named. Reproduce the upload flow in the resource panel, then trace the AJAX request that manages the available-resource list and inspect its browser-cache behavior. Done means a newly uploaded file appears in the available resources without a manual cache-clearing step or page reload.
