[squid-users] Squid.out reports errors for lines that do not exist in squid.conf

[Cheadle, Edward]

Squid version 3.5.27-1.el6
Linux:  Amazon Linux AMI 2018.03.0

I saw the warning messages below in squid.out, did some research and found out that the messagesseemed to be caused the two lines:
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32

From http://www.squid-cache.org/Versions/v3/3.5/cfgman/acl.html I see that both these two acl’s are now predefined and are not shown in the recommended configuration.
I suspect the person that installed squid for us found an older conf file from somewhere.

2018/06/06 20:49:29| WARNING: (B) '127.0.0.1' is a subnetwork of (A) '127.0.0.1'
2018/06/06 20:49:29| WARNING: because of this '127.0.0.1' is ignored to keep splay tree searching predictable
2018/06/06 20:49:29| WARNING: You should probably remove '127.0.0.1' from the ACL named 'localhost'


The FATAL error messages below  is because I added a line with dstdomain in it when there were already an entry with dstdom_regex in it.
I assume that is the “type” that is talked about.

2018/06/06 20:49:29| aclParseAclLine: ACL 'aws_s3' already exists with different type.
FATAL: Bungled /etc/squid/squid.conf line 254: acl aws_s3   dstdomain -n .s3.amazonaws.com

The issue is that I removed line 254 and I removed both of the lines above and yet I restart squid and continue to get these errors.

Does squid compile the rules and keep them somewhere, and I need to do something else than service squid restart to get rid of rules?
