I have a Squid cache server "Version 2.5.STABLE6" running on RedHat Enterprise Linux 4. It seems working fine so far, it has only been up for two days, except I can't access local web servers without using FQDN. For example, when I tried http://sharepoint, I received the following error messages: "The requested URL could not be retrieved While trying to retrieve the URL: http://sharepoint/ The following error was encountered: Unable to determine IP address from host name for sharepoint The dnsserver returned: Server Failure: The name server was unable to process this query. This means that: The cache was not able to resolve the hostname presented in the URL. Check if the address is correct. " I have the "append_domain" option configured to include the local domain. "[root@rcarhld02 squid]# grep qrs.com /etc/squid/squid.conf append_domain .qrs.com" Is there something else I missed? Also, I have another related question, can I append multiple domain names like "append_domain .localdomain1.com .localdomain2.com"? Thanks in advance for all the helps.
