PLZ help with access controls!

Hello, people,

I really need some help from squid gurus...

Can anyone explain me the internals of how acl based access control is
working. Here is a snippet of my squid.conf:

acl IN-CEN srcdomain
acl YRN-1 src

http_access deny IN-CEN
http_access allow YRN-1
http_access deny !YRN-1 all

miss_access deny IN-CEN
miss_access allow YRN-1

------------------- cut here ---------------------

This does not work as intended - that is * can still
connect to the cache server. Machines in * have IPs from
a subset of "YRN-1"

Is there an online resource which would explain how squid's ACLs work -
the order of evaluation, what happens to an address when it satisfies/
doesn't satisfy some rules, and simply how many lines with
http_access/miss_access, etc. are allowed in the config file?

Squid is a great piece of software, but the situation with access controls
(and lack of documentation on them) makes it less pleasant to use than it
deserves to be.

Thanks in advance,
