       [COLOR=#000084]var[/COLOR] request:URLRequest = [COLOR=#000084]new[/COLOR] URLRequest ("http[COLOR=#878787]//siteB/question.php");[/COLOR]
       request.method = URLRequestMethod.POST;
       [COLOR=#000084]var[/COLOR] variables:URLVariables = [COLOR=#000084]new[/COLOR] URLVariables();
       variables.tabelname = file;

       request.data = variables;
       [COLOR=#000084]var[/COLOR] loader:URLLoader = [COLOR=#000084]new[/COLOR] URLLoader (request);
       loader.addEventListener(Event.COMPLETE, onComplete);
       loader.dataFormat = URLLoaderDataFormat.VARIABLES;
       loader.[COLOR=#000084]load[/COLOR](request);[/LEFT]

               [COLOR=#000084]var[/COLOR] totalrecords=variables.total_records;
               enz..
       }
}[/LEFT]

error code

[COLOR=#999999]Error #2044: Unhandled SecurityErrorEvent:. text=Error #2140: Security sandbox violation: [/COLOR]

On my webserverB there is also a file “crossdomain.xml”.

crossdomain.xml


<?xml version="1.0"?>
<!DOCTYPE cross-domain-policySYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="siteA" />
</cross-domain-policy>

What do i do to get rid of the error message.
