The objects with authentication are never cached if :
1 - Squid doesn't have ignore-auth set in its configuration file
AND
2 - The web server hasn't sent "Cache-Control: public" in the response
header.

If webserver sends "Cache-Control: public" (or ignore-auth is set), the
first user downloading the object will require a valid authentication.
Next users won't need authentication if object is cached.

If webserver sends "Cache-Control: public, max-age=0", object is cached
but all users will require a valid authentication to the end server.
