这是在响应<一个href="http://stackoverflow.com/questions/3318645/how-do-i-know-if-the-request-came-from-flash-swf/3318721#3318721">John巴林杰的回答是：

import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLRequestHeader;

var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("http://www.mydomain.com/myapp.php");
var header:URLRequestHeader = new URLRequestHeader("custom-header-name", "value");
request.requestHeaders.push(header);
try {
    loader.load(request);
} catch (error:Error) {
    trace("Unable to load requested document.");
}

您还必须确保修改您的crossdomain.xml允许HTTP头如下：

You must also make sure to modify your crossdomain.xml to allow http headers as follows:

<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
    <allow-access-from domain="*.mydomain.com" />
    <allow-http-request-headers-from domain="*.mydomain.com" headers="*" />
</cross-domain-policy>
