I had a similar problem, which I think was being caused by other
software on the computer triggering the splash page (antivirus, updates
etc).
I found the most reliable way was to force the user to "accept" the
splash page before it was removed.
It was a while ago when I did this, but I've just looked back through my
code and in summary:
- I configured Squid as per [1] to show the splash page for a fixed
timeout using an external session helper. Ignore the comments about
recent patches - they are now in the stable Squid release.
- The splash page was created in PHP page with a button that when
"accepted" wrote to the external session helper's database
- Once the session's helper database had recorded the client's details
then it allowed the user access
<?php
$session_helper = 'sudo -u proxy /usr/lib/squid3/ext_session_acl -a -T 10800 -b /var/lib/squid/session';
if (isset($_GET['takemetothepage'])) {
$handle = popen($session_helper, 'w');
fwrite($handle, "10 " . $_SERVER['REMOTE_ADDR'] . " LOGIN\n");
pclose($handle);
header("Location: http://www.google.co.uk";);
exit;
}
// Your splash HTML here
?>
Click <a href="
<?php echo $_SERVER['PHP_SELF'] . "?takemetothepage"; ?>
">here</a> to continue.
