ext_file_userip_acl - Restrict users to certain IP addresses, using a text file backend.

       The squid.conf configuration for the external ACL should be:
              external_acl_typetype-name%SRC%LOGIN/path/to/ext_file_userip_acl-f/path/to/config.file

       If the helper program finds a matching username/ip in the configuration file, it returns OK  ,  otherwise
       it returns ERR.

       The configuration file format is as follows:
              ip_addr[/netmask]   username|@group|ALL|NONE

       Where ip_addr is a dotted quad format IP address, the netmask must be in dotted quad format too.

       When  the  second parameter is prefixed with an @ , the program will lookup the /etc/group file entry for
       the specified username.

       There are other two directives, ALL and NONE , which mean "any user on this IP address may  authenticate"
       or "no user on this IP address may authenticate".
