[squid-users] Yahoo Games can not show pages

Hi People

I am running squid for windows on an XP box.
The net access Internet, by Squid Proxy server directing the navigators to
the proxy.
The last page of Yahoo Games in this case Chess pages show the next:
Can not connect to the server
There are four possibles reazones

1.- You are behind a firewall (there are not a firewall)
2.- You are not connected to internet (It can goany where but yahoo-games)
3.- The games server is down (It can be accessed from the main box)
4.- You have a stale page in your cache *****

Is there a way to know if there is a stale page in Squid and how to fix it

Thanks in advance
