[RPC Fault faultString="Security error accessing url" faultCode="Channel.Security.Error" faultDetail="Destination: DefaultHTTP"]
 
HTTPService 데이터 연동 방법은 XML을 지원하는 모든 웹 프로그램에서 가능하다.
XML 데이터만 받아오면 무엇이든 가능하다.
 
주의 할 것은
자신의 로컬서버에 있는 swf 파일에서 다른 서버에 있는 리모트 데이터(XML)을 가져오려할 때 보안문제가 발생한다.
리모트 데이터 접근이 불가능하다.
 
http://aaa.bbb.com/test.html(swf)로 접속 후 XML 데이터를 가져올 때 URL이 http://aaa.bbb.com/data.jsp에서 작성된 XML이라면
동일한 로컬 데이터로 문제가 발생하지 않는다.
 
http://xxx.yyy.com/test.html(swf)로 접속 후 http://aaa.bbb.com/data.jsp를 호출 시 아래와 같은 예외가 발생한다.

리모트 서버의 접근을 허용하려면 crossdomain.xml에 접근하는 리모트 서버를 등록해야한다.
crossdomain.xml은 웹 서비스 루트 디렉토리에 작성한다.
