The following error was encountered: Unable to forward this request at this time. This request could not be forwarded to the origin server or to any parent caches. The most likely cause for this error is that: The cache administrator does not allow this cache to make direct connections to origin servers, and All configured parent caches are currently unreachable. Your cache administrator is webmaster. ________________________________ Generated Mon, 03 Jul 2006 05:52:48 GMT by Aptech (squid/2.6.STABLE1) but if i checked the tools-options-connection and fill the ip-proxy address, then the above error disappear. can anyone help me ?
