IE8：Internet Explorer无法打开此Internet站点。请求的网站不可用或无法找到 [英] IE8 :Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found

问题描述

这应该是关于IE8下载问题的老问题。我使用PHP来设置响应头像：

This should be a old problem about IE8 download problem. I used PHP to set the response header like:

header("Pragma: public");
header("Expires: 0"); 
header("Content-type: application/octet-stream");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Length: ".strlen($content));
header("Content-Disposition: attachment; filename='$filename'");

并且Fiddler接近连接。

and the Connection is close capture by Fiddler.

当我尝试在IE8（不在SSL中）下载带有上述标题的文件时，消息框：

When I try to download the file with above header in IE8 (not in SSL), the message box :

Internet Explorer无法打开此Internet网站。请求的网站不可用或无法找到。弹出并下载停止。

"Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found." pop up and download is stopped.

我在网上搜索并尝试了很多解决方案，但似乎没有一个有效。这个问题还有其他解决办法吗？

I searched on net and try lots of solutions but seems none of them works. Would there be any other solution for this problem?

PS：我试过：在标题中删除响应标题/重置contentType /将网站添加到可信站点/集Do不将加密的页面保存到磁盘为真。

PS: I have tried: Delete response header/reset contentType in header/ Add the site into trusted site/ set "Do not save encrypted pages to disk" as true.

谢谢。

推荐答案

除了Le-roy的回答：

In addition to Le-roy's answer:

我设置

Cache-Control: private, max-age=1

这为我解决了这个问题。

and that fixed the issue for me.

从Le-roy的链接中，如果设置了以下任何一个：

From Le-roy's link, if any of these are set:

Cache-Control header with the tokens no-cache, no-store
Vary header that specifies almost anything 
Pragma header that specifies exactly no-cache

IE下载失败。
