Hi,
We can help if you post specific queries, e.g.
We have dialup/ISDN connection, we installed squid, http proxy is not functional / caching does not occur.
You can also post you configuration files devoid of any private information such as IP addresses, email contacts etc.
That will produce more speedy results.
Best regards,
Rajesh
