After the Adobe Flash player upgrade to 9.0.124, due to security policy changes, so that in the socket or Xmlsocket applications, the original HTTP mode to load security policy can not continue to use, similar to such applications must use the Xmlsocket ://way to provide security policy. The Flashplayer security policy detection process is as follows:

1, first detect whether the target server port 843 provides a security policy

2, if 1 does not detect a policy, detects if ActionScript is using the

Security.loadpolicyfile (xmlsocket://)

means to provide a security policy, and if not detected, use the 3rd step detection

3, detects if the target server destination port provides a security policy
