Here's the code that should work:

{if $smarty.server.HTTPS ne "on"}
Your Script Code
{/if}

If it doesn't work, which it sounds like it's not, try this:

Open auth.php

At the very end, but before ?> put:

$smarty->assign("wcmServerport",$HTTP_SERVER_VARS['SERVER_PORT']);

Then in your smarty template use:

{if $wcmServerport eq "80"}
Your Script Code
{/if}
