if ($rewrite != 'active') {
    $mayimobile = array();
    $mayimobile['mobileuri'] = substr($city['mdomain'], 0, -1) . ($_SERVER['HTTP_X_ORIGINAL_URL'] ? $_SERVER['HTTP_X_ORIGINAL_URL'] : $_SERVER['REQUEST_URI']);
    if ($ifmobile) {
        write_msg('', $mayimobile['mobileuri']);
    }
}

$_SERVER['REQUEST_URI']， 这个用 "./".$_SERVER['REQUEST_URI']
//这两个地址是什么，你最好显示出来，不然有点不好确定     $_SERVER['HTTP_X_ORIGINAL_URL'] : $_SERVER['REQUEST_URI']
