No. What that header value is saying is that there are multiple
different objects that could be in this reply which depend on details
such as; TCP IPs and ports connected to the server, some background
random number generator, whether the server admin had coffee or tea this

the decision.
ETag which might answer revalidation requests is invalid and cannot be
used.
