Your request "Cache-Control: no-cache" requires that the cache not be
used. Only a MISS is permitted.

The reply "Cache-Control: private, max-age=0" additionally mandates that
this response is private fr the individual user making the request and
not be stored in any cache for more than 0 seconds.

I think what the remainder of the log is showing is that Squid attemts
to setup the Vary marker stuff in cache for this object. But the object
itself is not permitted to be stored, so nothing gets stored at the
location the Vary marker object points to.

Following requests then cannot find the object and log the warning.
