Accessing www.google.com from AS3 flash app - actionscript-3

Question

In my application, I am trying to display some data from google.com.
My problem is that I always have this error :
Error #2048: Security sandbox violation: https://XXXXX.com/runtime.swf cannot load data from http://www.google.com/finance/company_news?q=null:OZG&output=rss.
The crossdomain.xml of google looks like that:
<?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="by-content-type" />
</cross-domain-policy>
And I call the page in my AS3 code like that :
var hdr:URLRequestHeader = new URLRequestHeader("Content-type", "text/x-cross-domain-policy");
var request:URLRequest = new URLRequest(feedURL);
request.requestHeaders.push(hdr);
//then load the request with an UrlLoader
Do you have any idea of why flash give me this cross damin security error?

Answer 1

I actually misunderstood the meaning of the crossdomain.xml file. Basically, the crossdomain policy file of google doesn't allow any domain.
I think that my only solution is to use a proxy...

Answer 2

You can use a PHP proxy, but cURL must be enabled.
For example:
$gogle = curl_init();
curl_setopt($gogle , CURLOPT_URL, $googleurl);
curl_exec($gogle);
If you need further manipulations use the CURLOPT_RETURNTRANSFER option to return the content as a string instead of outputting it.
curl_setopt($ch, CURLOPT_RETURNTRANSFER , TRUE);
$content = curl_exec($ch);
use CURLOPT_POSTFIELDS if you need to pass POST agouments (eg: "param=value&q=google")
