Time for action – configuring Digest authentication

Therefore, an example HTTP Digest authentication with Squid will look similar to the following:

auth_param digest program /opt/squid/libexec/digest_file_auth
auth_param digest utf8 on
auth_param digest children 20 startup=0 idle=1
auth_param digest realm Squid proxy server at proxy.example.com
auth_param digest nonce_garbage_interval 5 minutes
auth_param digest nonce_max_duration 30 minutes
auth_param digest nonce_max_count 50
auth_param digest nonce_strictness on
auth_param digest check_nonce_count on
auth_param digest post_workaround on
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
http_access deny all
