[squid-users] maxconn acl setting??

Hello,
We're having problems with http scanning viruses chewing up all the
free file handles on the cache (which is currently set to 4096).. we'd
like to implement a per client IP max connections along the lines of 100
or 150.. our current ACL's are like:

acl client_net1 src a.b.c.0/18
acl client_net2 src d.e.f.0/18
acl client_net3 src f.h.i.0/19
acl client_net4 src j.k.0.0/20
acl client_net5 src l.m.0.0/16

is it possible to add a maxconn such that any individual IPs within these
ranges are limitted to 100 or so connections, or does that apply to the
entire ACL?? I don't want to have to add each IP as its own ACL.

Or maybe I'm confused, how exactly does maxconn work??

Thanks!
