[squid-users] external_acl_type and returned keyword

[Steve]

Hi All,

Squid 2.5 question:
In the case of external_acl_type, if the helper program returns
OK user=Bob
Will squid make use of this username? If yes, how?
Is it related to proxy_auth?

How bout in version 3? Making use of ext_user?

Thanks!
Regards,
Steve
