Dist, besides the actual name of the external helper program as 'an argument' of the [arguments...], what other kinds of data can we pass as arguments to the acl for an external helper. Secondly, on the external_acl_type ... [ helper arguments ... ] what squid variables/etc... can be passed as [ helper arguments...] ???
