<p>Squid supports reading configuration option parameters from external
files using the syntax <em>parameters("/path/filename")</em>. For example:
<verb>
- acl whitelist dstdomain parameters("/etc/squid/whitelist.txt")
+ acl allowlist dstdomain parameters("/etc/squid/allowlist.txt")
</verb>
<p>There have also been changes to individual directives in the config file.
