php - GSiteCrawler 服务器测试显示错误？

Question

在这段代码中，我给出了重定向 $searchLink

$urlCity = strtolower($_COOKIE['UserCityName']);
 $searchLink = '/properties-in-'.$urlCity.'.php'; 
 if($_SERVER['REQUEST_URI'] != $searchLink)
 {
    Header("HTTP/1.1 301 Moved Permanently" );
    Header("Location: http://".$_SERVER['HTTP_HOST'].$searchLink);   
 }

但是在 GSiteCrawler Server-Test 中显示错误

'http://legacy.com/properties-in-.php' 
Result code: 200 (OK / OK)

'http://legacy.com/properties-in-chennai.php'  like this it should come

我该如何解决这个问题
