Build option --with-default-user=proxy causes "cache_effective_user proxy" to be the built-in default. The only use that directive has is when sharing your build with someone else who doesn't want 'proxy' as their low-privilege user account. All directives not listed in squid.conf are optional and most of the documentation has been removed to squid.conf.documented and online at <http://www.squid-cache.org/Doc/config/>. What remains is the bare essentials and recommended security settings for a simple LAN proxy. Squid should work fine with just the default config file. If it doesn't that problem needs fixing before anything more complicated get added. The usualy first issues are making sure the LAN ranges are in the localnet ACL definition, the /dev/shm mounted, and nothing else running on Squid listening port.
