What are the various ways page redirects are generally done all over the internet ? Show me some code samples, if you may, as I need to teach my searchengine crawler to watchout for these codes and not index pages that got these redirects.
// get the redirection url from GET variable<br/> $redirect_to = !empty($<EM>_GET['url'])<br/> ? trim(strip_tags(stripslashes($_</EM>GET['url'])))<br/> : '';
$wait_time = 15000; // auto navigation time (in milliseconds - this is 30000 ml = 30s).<br/> $wait_seconds = $wait_time / 1000;
add_action('wp_head', 'redirect_to_no_index', 99);<br/> function redirect_to_no_index()<br/> {<br/> ?><br/> <!-- disable indexing this page --><br/> <meta name="robots" content="noindex, follow">
