Hi!
In a federated query on my own (Fuseki) endpoint,
which reaches out to
the Wikidata endpoint, with values already bound, it seems that I get
for each bound value an entry in the Fuseki log like this:
The header is not generated by the query service but probably is added
by Varnish. Not sure why Fuseki doesn't like the expires string - it
seems to be fine to me.
