Squid also supports a wide variety of caching protocols, such as Internet Cache Protocol (ICP), the Hyper Text Caching Protocol (HTCP), the Cache Array Routing Protocol (CARP), and the Web Cache Coordination Protocol (WCCP).

Squid can implement caching and proxying of Secure Sockets Layer (SSL) requests and caching of Domain Name Server (DNS) lookups, and perform transparent caching. Squid is a full-featured web proxy cache server application which provides proxy and cache services for Hyper Text Transport Protocol (HTTP), File Transfer Protocol (FTP), and other popular network protocols. We recommend that you have a 'deny all' entry at the end of your access lists to avoid potential confusion.Multi-node configuration with Docker-Composeĭistributed Replicated Block Device (DRBD) Conversely, if the last line is allowed, the default will be denied. If the last line was denied, the default is allowed. If none of the 'access' lines cause a match, the default is the opposite of the last line in the list. If the access operations are not specified in the configuration file, the access request will be denied. If there are no 'access' lines present, the default is to deny the request. The rules are checked one by one as they are added in the configuration file until a rule for the access subject is found.

http_access deny all - deny access for all.

http_access deny CONNECT !SSL_ports - deny CONNECT to all ports except for SSL.

http_access allow localnet - allow access for localnet.

!aclname - a rule will be applied to all subjects except for the access list. # Add any of your own refresh_pattern entries above these.Īclname - a list of access that the rule is applied to. #cache_dir ufs /var/spool/squid 100 16 256 # Uncomment and adjust the following to add a disk cache directory. # And finally deny all other access to this proxy # Adapt localnet in the ACL section to list your (internal) IP networks
