 IMS_HIT means Squid returned a 304 not modified reply without
forwarding the request to the origin server (true).

 But the why of your question is strange : given freshness information
 for objects, squid takes that into account and will
 not bother the remote webserver, if not needed.

 You can prevent certain sites from being cached, if you would
 need this for specific purposes.

 Checkout the 'no_cache' directive in squid.conf.default
