Thanks for the reply Amos. Please see my previous mail for a complete explanation of my requirements. http://www.squid-cache.org/mail-archive/squid-users/200904/0295.html I'm using Squid Cache: Version 3.0.STABLE13 I'm looking for a way to pass a variable to an external acl which must contain an already authenticated username. I can not use %LOGIN because squid will assume that it's an auth helper and prompt the user for re-authentication on ERR return and I want to return a custom page on ERR return. I just thought %EXT_USER will contain the username from and external auth helper. Conf example ======= auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp external_acl_type QuotaUser ttl=1 negative_ttl=0 children=3 %EXT_USER /sqm/bin/quota_user.pl acl password proxy_auth REQUIRED acl quota_user external QuotaUser http_access deny !password http_access deny quota_user http_access allow all deny_info ERR_CUSTOM_IN_QUOTA_USER quota_user -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: 15 April 2009 01:56 PM To: Bartel Viljoen Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: %EXT_USER value Bartel Viljoen wrote: > Dear Squid users. > > Does anyone have a working squid conf example of the %EXT_USER that is > available in squid 3.

So most cases it would not exist yet.

Then the value you are probably looking for is %LOGIN.
