HEAD request not returning ETAG and/or Last-Modified

We’re trying to build a mechanism that would only reach the CH API when the data has actually changed. One way of doing that would be to preflight the actual request with a HEAD request. Unfortunately there are no headers for Last-Modified or ETag stamps.

I think such functionality would be very helpful to all. Is this something you guys could add?

please see Etags in documentation, but not in resources

Thanks, I saw that, but currently the ETags are in response body, while in my opinion they really should be in the headers.

… so we can save on payload and computation (your side), provided you don’t have to fetch all data just to get the Etag/Last-Modified.
