Topic: If-None-Match for interactions other than read
Jim Steel (Feb 10 2017 at 00:46):
Is there a way to set the If-None-Match header for interactions other than read (e.g. vread, search, GET operations)? I found http://hapifhir.io/doc_rest_etag.html, and I explored the API a bit, but can only find support for ifVersionMatches() on read requests.

Using ifVersionMatches() is the only way currently (other than via a custom interceptor I suppose) but that covers read and vread.
Would you want that header anywhere else? FHIR doesn't really define a meaning for it for things like search..

Any idempotent operation could be cached. For example, a $lookup request on an unchanged code system.
