Steven 7b77415f3c Refactor image optimizer static immutable header (#25909) ... Previously we were accepting a `s=1` query string parameter for static imports, but this is not necessary. Instead, this PR looks at the file path to determine if the header should be `immutable`. The nice thing here is we don't need to worry about someone trying `s=1` with an external image or 3rd party loader. In that case, we use the upstream `Cache-Control` header as usual. This change also ensures we don't add the `immutable` header for `next dev`. Related to PR #24993		2021-06-08 22:05:02 +00:00
