I'm trying to use microsoft XDomainRequest to send cross domain request. Here is the code
我正在尝试使用 microsoft XDomainRequest 发送跨域请求。这是代码
... if ($.browser.msie && window.XDomainRequest) { // Use Microsoft XDR var xdr = new XDomainRequest(); xdr.open("POST", "http://graph.facebook.com/1524623057/"); xdr.send(); } ....
... if ($.browser.msie && window.XDomainRequest) { // Use Microsoft XDR var xdr = new XDomainRequest(); xdr.open("POST", "http://graph.facebook.com/1524623057/"); xdr.send(); } ....
It gives SCRIPT5: Access is denied.error on xdr.open(...)line.
它在线给出SCRIPT5: Access is denied.错误 xdr.open(...)。

I found the reason of this problem. As stated in Point 7:
我找到了这个问题的原因。如第 7 点所述：
Requests must be targeted to the same scheme as the hosting page
This restriction means that if your AJAX page is at
http://example.com, then your target URL must also begin with HTTP. Similarly, if your AJAX page is athttps://example.com, then your target URL must also begin with HTTPS.
请求必须针对与托管页面相同的方案
此限制意味着，如果您的 AJAX 页面位于
http://example.com，则您的目标 URL 也必须以HTTP开头。同样，如果您的 AJAX 页面位于https://example.com，那么您的目标 URL 也必须以HTTPS开头。

It describes how the server must respond with a certain header, Access-Control-Allow-Origin.
它描述了服务器必须如何响应某个标头 Access-Control-Allow-Origin。
