from the squid.conf documentation

        acl aclname referer_regex [-i] regexp ...
          # pattern match on Referer header
          # Referer is highly unreliable, so use with care

then there is also

        acl aclname req_header header-name [-i] any\.regex\.here
          # regex match against any of the known request headers. May be
          # thought of as a superset of "browser", "referer" and "mime-type"
          # ACLs.

and

referer_log

        Squid will write the Referer field from HTTP requests to the
        filename specified here. By default referer_log is disabled.
