    Security sandbox violation




             I have an application which upload/download files to/from box.net. the application works fine when not deployed on server but when I deploy it on Google App Engine the following error is encountered .


      Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://somexyz.appspot.com/xyzsample.swf cannot load data from http://box.net/api/1.0/download/abcdef/123456.


      I have included the below lines of code in as3



      and placed crossdomain.xml in app root folder (Google App Engine) and can access the file using http://somexyz.appspot.com/crossdomain.xml


      crossdomain.xml contains the below lines


      <?xml version="1.0"?>

      <!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd">


         <site-control permitted-cross-domain-policies="all"/>

         <allow-access-from domain="*" to-ports="*"/>

         <allow-http-request-headers-from domain="*" headers="*"/>

         <allow-http-request-headers-from domain="*"/>



      I am also getting the same issue when I tried using tomcat 


      Please help me to figure out a solution .


      Thanks in advance.
