IE / FF上缺少HTTP Referrer信息（在Chrome / Safari上运行良好）
[英]Missing HTTP Referrer info on IE/FF (works well on Chrome/Safari)
问题描述
I have page1.php with this code: 
我有使用此代码的page1.php ：
<form action="/redirect.php" method="POST" target="_blank">
<input name="destination" type="hidden" value="a"/>
<input type="submit" value="Click here"></form>
and this is redirect.php : 这是redirect.php ：
<?php
$url = "http://www.default.com";
if(isset($_POST['destination'])){
switch ($_POST['destination']) {
case "a":
$url = "http://www.domain1.com";
break;
case "b":
$url = "http://www.domain2.com";
break;
default:
$url = "http://www.default.com";
}
}
header( "refresh:1;url=$url" );
?>
<!doctype html>
<html>
<head>
</head>
<body>
<div>Redirecting, Please wait</div>
</body>
</html>
I've created the redirect page this way because it's important for me that it would load and display certain content, rather than redirect straight away (and thus, it yields out a 200 code, rather than a 302 code). 我以这种方式创建了重定向页面，因为对我来说重要的是它将加载并显示某些内容，而不是立即进行重定向（因此，它产生的是200代码而不是302代码）。
However, only on Chrome and Safari, the Headers of the redirect contain information about the referring url, which is redirect.php , and thus, for example, the owner of domain1.com will know that the visitor came from mydomain.com/redirect.php . 但是，仅在Chrome和Safari上，重定向的标头包含有关引用网址的信息，即redirect.php ，因此，例如， domain1.com的所有者将知道访问者来自mydomain.com/redirect.php 。
But on IE and FF, the referrer in the headers is null. 但是在IE和FF上，标头中的引荐来源网址为null。 What is causing this different behavior and how can I fix it to have them carry the same referrer info as well? 是什么导致了这种不同的行为，我如何解决它以使它们也携带相同的引荐来源信息？

您可以尝试：
header("Location: ".$url."");

Working example (tried on FF 27.0.1): 工作示例（在FF 27.0.1上尝试）：
File page1.php : 文件page1.php ：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Starting page</title>
</head>
<body>
<form action="redirect.php" method="post">
<input type="hidden" name="destination" value="a">
<input type="submit" value="Click here">
</form>
</body>
</html>
File redirect.php : 文件redirect.php ：
<?php
$url = "http://www.default.com";
if(isset($_POST['destination'])){
switch ($_POST['destination']) {
case "a":
$url = "http://www.domain.com";
break;
case "b":
$url = "http://www.examples.com";
break;
default:
$url = "http://www.example.com";
}
}
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Landing page</title>
</head>
<body>
<div>Redirecting, Please wait</div>
<script>
window.onload = function() {
setTimeout(function(){
window.location = '<?php echo $url;?>';
}, 4000);
};
</script>
</body>
</html>
How it's working: After clicking the button Click here on page1.php , the post data is sent and the domain http://www.domain.com is chosen. 如何它的工作：点击按钮后Click here上page1.php ，后的数据发送和域http://www.domain.com选择。 With javascript, after 4 seconds after window onload, the browser will redirect the user to http://www.domain.com . 使用javascript，在窗口加载后4秒钟后，浏览器会将用户重定向到http://www.domain.com 。 I have watched the referer headers in Firebug and they were sent. 我已经看过Firebug的引荐来源标头，并且这些标头已发送。

Confused. 困惑。 Redirect and page refresh is not equally. 重定向和页面刷新并不相同。 And more - not all browsers support refresh header. 还有更多-并非所有浏览器都支持刷新标头。
