[Plugin: Page Links To] url parameters

looking for redirecting with original parameters

i tried to modify the original plugin source ( version 2.7.1 ) :

/**
	 * Performs a redirect, if appropriate
	 */
	function template_redirect() {
		if ( !is_single() && !is_page() )
			return;

		global $wp_query;

		$link = get_post_meta( $wp_query->post->ID, '_links_to', true );

		if ( !$link )
			return;
		/* begin Modification */
                if($_SERVER['QUERY_STRING']) {
                      $link .= '?' . $_SERVER['QUERY_STRING'];
                 }
                /* end modification */
		wp_redirect( $link, 301 );
		exit;
	}

and works.. but maybe i′m missing something.

Thanks all for your work.
