This comes from squid.conf.
I beleive this is what you're looking for.
just set up the propper acls and you should be away.

# Usage: always_direct allow|deny [!]aclname ...
#
# Here you can use ACL elements to specify requests which should
# ALWAYS be forwarded directly to origin servers. For example,
# to always directly forward requests for local servers use
# something like:
#
# acl local-servers dstdomain my.domain.net
# always_direct allow local-servers
#
# To always forward FTP requests directly, use
#
# acl FTP proto FTP
# always_direct allow FTP
#
# NOTE: There is a similar, but opposite option named
# 'never_direct'. You need to be aware that "always_direct deny
# foo" is NOT the same thing as "never_direct allow foo". You
# may need to use a deny rule to exclude a more-specific case of
# some other rule. Example:
#
# acl local-external dstdomain external.foo.net
# acl local-servers dstdomain foo.net
# always_direct deny local-external
# always_direct allow local-servers
#
# This option replaces some v1.1 options such as local_domain
# and local_ip.
# TAG: never_direct
# Usage: never_direct allow|deny [!]aclname ...
#
# never_direct is the opposite of always_direct. Please read
# the description for always_direct if you have not already.
#
# With 'never_direct' you can use ACL elements to specify
# requests which should NEVER be forwarded directly to origin
# servers. For example, to force the use of a proxy for all
# requests, except those in your local domain use something like:
#
# acl local-servers dstdomain foo.net
# acl all src 0.0.0.0/0.0.0.0
# never_direct deny local-servers
# never_direct allow all
#
# or if squid is inside a firewall and there is local intranet
# servers inside the firewall then use something like:
#
# acl local-intranet dstdomain foo.net
# acl local-external dstdomain external.foo.net
# always_direct deny local-external
# always_direct allow local-intranet
# never_direct allow all
#
# This option replaces some v1.1 options such as inside_firewall
# and firewall_ip.
