file_get_contents无法打开流：HTTP请求失败！ HTTP / 1.1 463

Question

I am trying to get RSS from other sites. They all work fine using file_get_contents except one link give me this error:

Warning: file_get_contents(http://alwatan.kuwait.tt/rss.ashx): failed to open stream: HTTP request failed! HTTP/1.1 463

I download all files and all have:

<rss version="2.0">

but the link with error have:

<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

this is the only difference between them.

Looks to me that that feed is not allowing you to grab it.

463 Restricted Client: This resource is not available for access by your client software. This request has been blocked. Please retry your request from a different client.

DOSarrest Internet Security is a cloud based fully managed DDoS protection service. This request has been blocked by DOSarrest due to the above violation. If you believe you are getting blocked in error please contact the administrator of scripts.local to resolve this issue.

You can test this by trying to use a curl instead of file_get_contents

<?php

$ch = curl_init("http://alwatan.kuwait.tt/rss.ashx");

curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
curl_setopt($ch, CURLOPT_USERAGENT, "spider");

curl_exec($ch);
curl_close($ch);

?>

As Aziz mentioned, if you set the agent and the referred, you can get through.
