some help about acls(not connected directly to squid )

i want to implement some acl code in my software and was wondering for help.
my main problem is that i'm not familiar with c or c++ so i cant just
peek at squid code to understand what i want.

my first thing is that when even trying to thing about a pseudo for acl
checks code i am getting a bit confused.

while reading on squid-users i understood that dstdomain acl is faster
then regex but i dont really know how they defer from each other on the
implementation.
i can think of a reverse order look-up on the domain instead of just
regex and a ".word" or "word.word" as a distinguish between a "match all".

also i have noticed in the dev list that was discussed about acl that do
not match change of code but i kind of lost it.

i'm almost sure i have read something about rfc for acl and i have seen
that exist this "http://www.ietf.org/rfc/rfc2086.txt" rfc but not really
sure where to start.

if anyone can give me some leads on even how to start thinking about acl
logic\pseudo or a document that talks about acls logic i will be more
then just happy.

Thanks,
Eliezer
