 Will happen if the object has been fetched once, and can
be considered fresh at the time a subsequent request for that
object is made through SQUID.

 Squid doesn't do this. Only upon a client request for that object.

 Squid doesn't do this, because the whole process of fetching a possible
 new version of an object is client driven.

 Your feeling is wrong, this that is not a standard Squid concept.
 If a cache becomes an active device in the context of what it's job
is,
 it may defeat it's purpose, that is reducing Internet traffic.

 In principle the process is client driven , making the cache 'silent'
 if no objects need to be fetched.
