Redirect Query

[sfields477]

Hi - I have an ecommerce website written in php. I've no experience and just starting to learn. On each product page there is a link to an internal web page, that correctly display in the address bar as http: when the link is clicked though it goes to https: I think I've found the script that controls it but can't see why it redirects through the SSL

<?php
    }

    if (tep_not_null($product_info['products_url'])) {
?>
      <tr>
        <td class="main"><?php echo sprintf(TEXT_MORE_INFORMATION, tep_href_link(FILENAME_REDIRECT, 'action=url&goto=' . urlencode($product_info['products_url']), 'NONSSL', true, false)); ?></td>
      </tr>
      <tr>
        <td><?php echo tep_draw_separator('pixel_trans.gif', '100%', '10'); ?></td>
      </tr>
<?php


Any help is gratefully appreciated.
