Recreating PoC problem

Hello, awesome method you posted there. Trying to reproduce it in our lab, avoided most of your fool-proof traps, but stuck at callback - in your github example onhook function just dont invoke jscallback. But crossdomains.xml request successfully applies.

Start with the GitHub example's onhook function and the jscallback path described in the report, then compare it with the successful crossdomains.xml request. Reproduce the callback behavior and determine what outcome should demonstrate that the callback is invoked.
