How do I solve Error: [strict] Ignoring policy file at http://my.domain.com/crossdomain.xml due to bad Content-Type 'binary/octet-stream'?

Question

This is an ActionScript 3 problem...

I am hosting a swf on my.domainA and I am requesting a jpg from my.domainB ( of course I'm obsfucating the domain names ) the using this code:

var request:URLRequest = new URLRequest(result.image); request.requestHeaders.push(header); var context:LoaderContext = new LoaderContext(true, ApplicationDomain.currentDomain, SecurityDomain.currentDomain); content = new Loader(); content.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoaded); content.load(request, context);

Domain B has a cross domain xml file which looks like this:

" " - having problems getting stackoverflow to show the xml but it's standard allow-access-from domain="*" policy file

However, I get this error: "Error: [strict] Ignoring policy file at my.domainB.com/crossdomain.xml due to bad Content-Type 'binary/octet-stream'. See www.adobe.com/go/strict_policy_files to fix this problem."

Does anyone have any idea how I can resolve this? Is this bad Content-type for the crosdomain.xml file or the jpg I am requesting?

Any help appreciated.

Answer 1

A first guess would be that your crossdomain file is being rejected, rather than the jpg.

In your code we can't see the content of your header variable... could the problem come from the way your request is handled?

Have you tried a simpler approach? Something like: var request:URLRequest = new URLRequest(result.image); var content:Loader = new Loader(); content.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoaded); content.load(request, new LoaderContext(true));

I've done some more research into this problem and I can't find anything the same, however using a content delivery network such as Akamai may be contributing to the problem: http: / / jessewarden.com/2009/03/handling-crossdomainxml-and-302-redirects-using-netstream.html

I've tried changing my code so there is no request for content and all I am doing is requesting the crossdomain.xml:

var policyFileURL:String = "http://resources-ms-ak.myDomainB.com/crossdomain.xml"; Security.loadPolicyFile(policyFileURL);

Unfortunately I still get: Error: [strict] Ignoring policy file at http: / / resources-ms-ak.myDomainB.com/crossdomain.xml due to bad Content-Type 'binary/octet-stream'

Again, any ideas people? :-S

I've never had this problem, but the message seems to indicate that the problem is that the crossdomain file is served with the wrong content-type (binary/octet-stream instead of text/xml). Can you check that? A simple way would be loading the xml with looking at the response headers with firebug (or some other tool).

By the way, you are loading an image. Probably you are aware of this, but just in case: if you don't need to manipulate the image pixel data, you can just load it without a crossdomain. Just don't try to create a BitmapData image from it and don't access loader.content either. Place the image on the display list (or remove it) through the loader object, that is a display object and can act like a "proxy" for the real image.
