It may be impossible to briefly answer such a general question, but if
you want to learn about Squid ACL processing in general, consider
starting with a specific ACL-driven directive use, followed by the base
ACL class, a simple specific ACL implementation, and ACL registration code:

* $ git grep -3 Config.accessList.spoof_client_ip
* src/acl/Acl.{h,cc}
* src/acl/LocalPort.{h,cc}
* src/AclRegs.cc


If you have a specific problem that you need to solve, please consider
detailing your question in that direction. I also recommend researching
your own question first and posting the results of that research along
with the description of the biggest problem you could not solve.

Finally, please start a new email thread for each new question.


HTH,

Alex.
P.S. Modern Squids do not use .c files for ACLs because most of the
modern code is written in C++.
