I had a problem when accessing a specific website.
Here is the log:
The requested URL could not be retrieved
Unable to determine IP address from host name for
www.####.com
The DNS server returned:
Name Error: The domain name does not exist.
This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.
Your cache administrator is webmaster.
here is my squid.conf file:
