Security.PrefetchSocketPolicy problem.

In testing, I got a error about corssdomain.

ErrorCode

• SecurityException: Unable to connect, as no valid crossdomain policy was found **

My crossdomain policy ...

<cross-domain-policy> <allow-access-from domain="*" to-ports="*"/> </cross-domain-policy>

I made 'socket server' as follows... (client unity is webplayer version)

1) Policy-server : If unity API(Security.PrefetchSocketPolicy ) call policy, will send crossdomain policy.
2) server1 : check users login
3) server2 : play game

TEST 1* (Success - different IP & using default 843 port)

1. Load unity Webplayer.

2. unity call 'Security.PrefetchSocketPolicy( 1.1.1.100, 843)'

3. Policy-server send cross-domain info.

4. connect Server1 ... Success

5. And then... move server (server has different ip)

6. API call 'Security.PrefetchSocketPolicy( 1.1.1.200, 843)'

7. Policy-server send cross-domain info.

8. connect Server1 ... Success.

TEST 2* (Fail - different IP & using 9999 port)

1. Load unity Webplayer.

2. unity call 'Security.PrefetchSocketPolicy( 1.1.1.100, 9999)'

3. Policy-server send cross-domain info.

4. connect Server1 ... Success

5. And then... move server (server has different ip)

6. API call 'Security.PrefetchSocketPolicy( 1.1.1.200, 9999)'

7. Policy-server send cross-domain info.

8. connect Server1 ... Fail.

9. Return Error : SecurityException: Unable to connect, as no valid crossdomain policy was found

"TEST-1" is Success. (no problem)
- Server1's IP is 1.1.1.100
- Server2's IP is 1.1.1.200
- Call 843 port for cross-domain info.

"TEST-2" is Fail !!!!!
- Server1's IP is 1.1.1.100
- Server2's IP is 1.1.1.200
- Call 9999 port for cross-domain info.

what is wrong?

Please help me~~~ :)

Thank you for read my question ^^

More info~~ :)

Policy-Server (send crossdomain info to unity) is open 9999 port.

A machine (IP 1,1,1,100)
- Policy-server open 9999 port
- Server1 open 11111 port

B machine (IP 1,1,1,200)
- Policy-server open 9999 port
- Server2 open 11111 port

Process step...
1. Unity webplayer connect Policy-Server's 9999 port for receive crossdomain info. (A Machine)
2. connect Server1
3. move Server1 -> Server2
4. connect Policy-Server's 9999 port for receive crossdomain info. (B Machine)
5. connect Server2
6. But, unity can not connect Server2 .....

If Policy-Server's port is 843(default), that process(move machine) is success.
But, If Policy-Server's port is changed(9999), that process(move machine) is fail.

If do not move (A machine -> B machine), it is success.

Unity only access A machine, or only access B machine is Success. But, unity access A machine and then access B machine is Fail.


What is problem?^^
