cache:clear:etag

Expires every cached ETag value stored in Redis, forcing the API to recompute conditional-request responses (If-None-Match / 304 Not Modified checks) from scratch instead of relying on previously cached ETags.

Takes no arguments or options. It scans Redis for all keys matching etag:* and expires them immediately; it does not touch any other cached data. Use this after changes that could make existing ETags stale in a way the application itself doesn’t detect - for example after directly editing data in the underlying databases outside of the API.
