Http_access allow accesses_from_back_office If you wanted to use an OR and say either accesses from the back office or accesses to are allowed then the line would look like this: http_access allow accesses_to_ This would look like this: http_access allow accesses_to_ accesses_from_back_office
Let’s say you want to allow access to only for the back office. And finally all other accesses would be denied. Then it would allow accesses from everyone to every web site during lunch time. For everyone else it will deny accesses to porn URLs. This would allow accessing from the admins (whatever that ACL looks like – probably a src ACL pointing to the subnet where the admin workstations are in). Http_access allow accesses_during_lunchtime Įxample: http_access allow accesses_from_admins The general syntax of an http_access line is: http_access (allow|deny) acl1 acl2 acl3. It then either accepts or denys depending on your setting. For each request that Squid receives it will look through all the http_access statements in order until it finds a line that matches. It works similar to the way a firewall would handle rules. The most useful feature is the http_access statement. ACLs can be used in various places of your nf. Using the ACLs: http_accessĭefining the ACLs alone does not actually block anything – it’s just a definition. The quotes are important here to tell Squid it needs to look up definitions in that file. Then the ACL for that file would look like: acl accessess_to_search_engines dstdomain "/etc/squid/search-engines-urls.txt" Let’s assume you have a list of search engines URLs that you want to allow: /etc/squid/search-engines-urls.txt: You can also use lists of definitions that are stored in files on your hard disk. Īcl accesses_from_marketing_department src 10.52.0.0/16 Īcl accesses_to_search_engines dstdomain. Įxamples: acl accesses_to_google dstdomain. The syntax of an acl is: acl name type definition1 definition2 definition3. The complete list of ACLs can be found at There are certain types of ACLs for that purpose. But they offer a great way of controlling who is allowed to access which web pages when.įirst you need to define certain criteria like accesses from the marketing department or accesses to or need to authenticate.
