There's no way for SQUID to know, it matches the same object,
SQUID only uses the complete url to decided on that. (MD5 - checksum)

Whether cached copies will be returned, if already accessed,
(from the same 'uniq' server); also depends on freshness info provided
by the webserver ,about the returned object.

What if, in both cases , the webserver issues a 'Cache-control:
no-cache ' header.
Then you question collapes by definition.
