[squid-users] Trying to implement Portal Splash

Using Debian platform with 2.6.STABLE14, and am following the config example found at http://wiki.squid-cache.org/ConfigExamples/Portal/Splash
I cannot seem to make this work.
The config example says...

Paste the configuration file like this:

# mind the wrap. this is one line:
external_acl_type session ttl=60 %SRC /usr/local/sbin/squid/squid_session -t 7200 -b /etc/squid/session.db

acl new_users external session

deny_info http://example.com/splash.html new_users

http_access deny !new_users

For the Debian package I had to modify the path to squid_session, else squid would not start. No big deal. Correct path for my system was: /usr/lib/squid/squid_session

I also changed the deny_info target to a valid splash page on an accessible server. I made sure that the splash page can be loaded by any client if accessed directly.

...the config example then goes on to say...

"This is just the snippet of config which causes the splash page and session to be enacted. Rules which permit the visitor use of the proxy are expected to be placed as appropriate below them. The basic default safety nets should as always be above them."

This seems a bit ambiguous for people who are new to squid (like me). I have tried pasting the block of code in various places in my config file, and it seems no matter where I put it, I get the same result from IE: "The page cannot not displayed, Diagnose Connection Problems".

Squid and AUTH works perfectly otherwise. Ideally, I want a splash page that displays our AUP, and has a form for username and password. Upon entering a valid username and password, acceptance of the AUP id confirmed and access to the proxy is granted.

TIA! Jim

My squid.conf follows:
