You need a little program which keeps track of the sessions. This silly
perl program should do:

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

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

Then use this with the external_acl_type directive in squid.conf with a
very short negative ttl.. then use deny_info to have the user redirected
to the policy page if not matching this acl.

external_acl_type session ...
acl session external session

http_access deny !session
deny_info http://your.web.server/policy.html session

inserted before where you allow access.
