It is good to know.

Ok lets go with some examples.

acl ip src 172.16.1.198
<other acl's>
http_access allow ip
<other http_access rules>

design for close_connections may be like

Regarding to your requirement of closing the connection of acl then,
close_connections allow | deny ip

if you specify as
    close_conntections allow ip
then
    you have to make the environment as
    http_access allow ip
    <snip other http_access rules>

if
    close_conntections deny ip
then
    you have to make the environment as
    http_access deny ip
    <snip other http_access rules>

It must be done with very high attention on the acl rules.You are going to change the access
environment

we are having some objects in the cache ,After squid reconfigure , acl of
acl manager proto cache_object
must be denied to the access of denied close_connection acl.

If you are using as close_connections deny <acl-name> then
    manager acl must be denied to that acl ..

Detailful and analysed design from all will make this as very much usefull.
