KRPano unable to load certain resources when the URL is constructed with parameters.

The below code fails and the layer is forever loading. Setting the url again when its in this stuck state causes krpano actions to stop working.
Environment: Flash+Chrome|Firefox etc.

Code

set(layer[test].url,https://graph.facebook.com/547734552/picture?type=normal);

The below code works without issue.

Code

set(layer[test].url,https://graph.facebook.com/547734552/picture);

Sometimes the following WILL work. In some cases it will not.

Code

set(layer[test].url,https://graph.facebook.com/547734552/picture);
set(layer[test].url,https://graph.facebook.com/547734552/picture?type=normal);

Hi,

that's a problem related to Flashplayer security.
Try to use/install the DEBUG Flashplayer to see the problem in detail.

The content returned from that server when using the query doesn't allow to be accessed.

Best regards,
Klaus

That's confusing still.

krpano does not throw and security errors.
I can pull down the resource in chrome directly.

https://graph.facebook.com/547734552/picture?type=normal

facebooks crossdomain.xml looks good.

I can load the query resource by loading another one without a query first usually
I can load the query resource by redirecting to it as.

krpano not, but the Flashplayer and you would need to use the DEBUG Flashplayer to be able see it (popup window).

There is a VERY BIG difference between Chrome and the Flashplayer and additionally also between direct requests and Javascript/Flash requests!

It seems the Flashplayer isn't requesting the crossdomain.xml files in this case.
Try to specify them manually by adding this code:

Code

<security>
  <crossdomainxml url="https://graph.facebook.com/crossdomain.xml" />
  <crossdomainxml url="https://fbcdn-profile-a.akamaihd.net/crossdomain.xml" />
</security>

Best regards,
Klaus

That appears to work!

So how come it works on the link without the "?" or by doing the preload trick or by redirecting?
Both links go to the same cdn domain.
Mystifying.

Please ask me something easier!
That Flashplayer crossdomain security stuff is always a bit special...
