尽管crossdomain.xml AS3加载器导致securityError＃2044

Question

我正在处理在线绘画应用程序。

应用程序SWF以及后端服务器位于： http://217.150.244.137/Client.swf

有位于根以及一个的crossdomain.xml： http://217.150.244.137/crossdomain.xml

我从服务器加载画布图像像这样：

var _loader:Loader = new Loader(); 
//make sure it's really not comming from the cache 
var urlRequest:URLRequest = new URLRequest(url+'?nocache=' + new Date().getTime()); 
var requestHeader1:URLRequestHeader = new URLRequestHeader("pragma", "no-cache"); 
var requestHeader2:URLRequestHeader = new URLRequestHeader("Expires", "Thu, 01 Jan 1970 00:00:00 GMT, -1"); 
var requestHeader3:URLRequestHeader = new URLRequestHeader("Cache-Control", "no-cache, no-store, must-revalidate"); 
urlRequest.requestHeaders.push(requestHeader1); 
urlRequest.requestHeaders.push(requestHeader2); 
urlRequest.requestHeaders.push(requestHeader3); 
var context:LoaderContext = new LoaderContext(true); 

_loader.load(urlRequest, context); 
_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onLoadError); 
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDataLoaded); 

不过，SWF不会

另一页embeeded工作时

我得到一个

Error #2044: SecurityErrorEvent unverarbeitet. text=Error #2170: Verletzung der Sicherheits-Sandbox: http://www.pictonauts.theaterspektakel.ch/Client.swf kann keine HTTP-Header an http://217.150.244.137/images/wall/4/img_-2_-1_4.jpg?nocache=1331058396137 senden. 

我缺少什么或者做错了吗？

首先，试试这个的crossdomain.xml：

<?xml version="1.0"?>  
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"> 
<cross-domain-policy> 
    <site-control permitted-cross-domain-policies="all"/> 
    <allow-access-from domain="*" to-ports="*" secure="false" /> 
    <allow-http-request-headers-from domain="*" headers="*" secure="false" /> 
</cross-domain-policy>
