SquidTL allows proxy administrators to manage proxy users: define how much time users can spend on a specific Web site, block sites, limit total time users can spend on the Web daily, and watch users' activity. For example, you can limit the use of Facebook or other social networks with per-user rules or IP. It has a small memory footprint and very fast execution. Management can be done with a smart Web-based administration GUI.
KnProxy Lambda is a branch of KnProxy that uses Java and PHP to provide users with a safe and balanced proxy service. Communications between the Java client and the PHP based server are encrypted in highly secure encryption methods. Traffic is also distributed among many servers to prevent flow monitoring. KnProxy Lambda allows users to set up a full proxy processing POST, GET, and AJAX Requests on any server offering PHP. It is also compatable with APJP servers, allowing for a wider network and an easier migration.
