//add one of the following <noscript> into the top of the <body> to trigger the above file. The first uses placeholders for page data, and the second shows how that data can be passed using WordPress.
//<noscript>
//<iframe class="hidden" src="includes/no-js.php?h=HOME_URL&amp;p=PAGE_URI&amp;t=PAGE_TITLE" width="0" height="0" style="display:none;position:absolute;"></iframe>
//</noscript>
// Notes: Use server-side scripting to fill in the HOME_URL, CURRENT_PAGE_URI, and PAGE_TITLE. Be sure to encode the page title to avoid spaces! If you are using Wordpress, you can use the following snippet:
//<noscript>
echo <iframe class="hidden" src="<?php echo get_template_directory_uri(); ?>/includes/no-js.php?h=<?php echo home_url('/'); ?>&amp;p=<?php echo get_page_uri(); ?>&amp;t=<?php urlencode(get_the_title()); ?>" width="0" height="0" style="display:none;position:absolute;"></iframe>
//</noscript>
