SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: cannot access

Question

When we try to print the Google Map API for Flash component, it is throwing the Security Sandbox Violation
      SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://ps6143:8080/aa/XYZ/Main.swf/[[DYNAMIC]]/1 cannot access  http://mt1.google.com/vt/lyrs=m@171000000&hl=en&src=api&x=1&y=1&z=1&s=Gali&flc=x3t. No policy files granted access.
at flash.display::BitmapData/draw()
To avoid this error we tried to use the alternate API provided by library. But that also causing cross domain issue as it loading some 3d library internally which is not able to access our application.
SecurityError: Error #2121: Security sandbox violation: BitmapData.draw: http://maps.googleapis.com/mapfiles/lib/map_1_20_10_3d.swf cannot access http://ps6143.persistent.co.in:8080/dv/SiteOptimizer/SiteOptimizer.swf/%5b%5bDYNAMIC%5d%5d /1http://ps6143:8080/aa/XYZ/Main.swf/[[DYNAMIC]]/1. This may be worked around by calling Security.allowDomain.
at flash.display::BitmapData/draw()
Please help us in resolving this issue.
Thanks & Regrds,

There is no redirect... Charles is a web proxy so it will look completely legitimate to the browser.
According to the help, it's getting the access request from the SWF itself and not the crossdomain.xml file:
In the case of a source object other than a loaded bitmap, the source object and (in the case of a Sprite or MovieClip object) all of its child objects must come from the same domain as the object calling the draw() method, or they must be in a SWF file that is accessible to the caller by having called the Security.allowDomain()method.
http://help.adobe.com/en_US/ActionScript/3.0_ProgrammingAS3/WS5b3ccc516d4fbf351e63e3d118a9 b90204-7d1b.html#WS5b3ccc516d4fbf351e63e3d118a9b90204-7c4a
So the default state accessing a SWF on a different domain is protected, unless that SWF allows some or all domains to access it via the Security.allowDomain() method.
