[This trouble really happened.]

Now, you foreigner must be connected to poj via Chinese proxy.
And there is a serious problem, when you use poj system.

Some data that you accessed poj are left to the proxy server's cache.
If somebody will access it through proxy same as you,
 your personal information left to a server may be seen.

I think poj can not control to proxy server's cache.
Therefore a foreigner using Chinese proxy has to be careful till poj completely revives!!

• Sorry about the trouble... We are also seeking for the reason why connection from outside China is frequenctly cut... (512) frkstyc 2006-10-11 22:12:59
