acl load ip list from file

[Melissa MacKenzie <unstablefears@xxxxxxxxx>]

Hello,

I'm wondering if it's possible to create an acl for IP only access by
loading a file of listed IPs.  I seen this is available for URL's via a
url_regex.  Not quite sure if it's possible via IP.

for example:

acl TrustedIP src "/usr/loca/squid/iplist"
http_access allow TrustedIP

Then iplist would have each new IP on a separate line it reads from?

Thanks!
