This issue is automatically created based on existing pull request: #39484: Update use cache control immutable for static site

Description (*)

Update Cache-Control header to static file (assets, media)
As explained in the Mozilla documentation:
``When a user reloads the browser, the browser will send conditional requests for validating to the origin server. But it's not necessary to revalidate those kinds of static resources even when a user reloads the browser, because they're never modified. immutable tells a cache that the response is immutable while it's fresh and avoids those kinds of unnecessary conditional requests to the server.`
