I am trying to create a start page so that Squid will display a disclaimer when clients login.
I found the following script on a previous posting, and put it on my server:

#!/usr/bin/perl
$|=1;
my %logged_in;

while(<>) {
  if (!defined($logged_in{$_})) {
    $logged_in{$_} = 1;
    print "ERR\n";
  } else {
    print "OK\n";
  }
}


This never "expires" sessions from the hash "logged_in". The following hack would at least help there:

#!/usr/bin/perl
$|=1;
my %logged_in;
my $session_ttl = 3600;
my $time = time();

while(<>) {
if ((!defined($logged_in{$_}) || ($logged_in{$_} + $session_ttl > $time)) {
   $logged_in{$_} = $time;
   print "ERR\n";
 } else {
   print "OK\n";
 }
}


No promises that it won't set your hair on fire, or scratch your CD's, etc.

I gave it proper permissions, and then put the following in my squid.conf:


external_acl_type session negative_ttl=0 %LOGIN /usr/lib/squid/my_squid_session.pl
acl session external session
http_access deny !session
deny_info http://##.##.##.##/startpage.php session


Using this configuration, the script will redirect the client the first time logging in, but not
again. Even 24 hours later and after deleting cookies, if I login again I am not redirected. I
have to restart squid in order to get another redirect to take place.

So I changed the first line to:
external_acl_type session ttl=300 negative_ttl=0 %LOGIN /usr/lib/squid/my_squid_session.pl

That doesn't seem to make a difference.
Any ideas? I am trying to avoid using the "squid_session" helper because I get all sorts of errors
when using it together with digest_authentication.

That's very odd.  I have no insight here, I just find it odd.

Thank you!
