特殊端口列表
A security change has been made in Adobe Flash Player 9.0.115.0 to block commonly reserved ports (to prevent malicious activity).
If a port number is specified at the end of a URL (such as http://www.adobe.com:80), the port will be checked against a list of commonly reserved ports.
If the port matches the following list, the network request will be rejected and a securityError event will be fired.
The following ports are considered reserved:
