Proxy Switch is designed for automatic switching of proxy servers used. It allows to distribute the load over a number of proxy servers as well as to remain anonymous on the Internet. Proxy Switch loads proxy server lists from standard text files and keeps successful/unsuccessful connection statistics for each of them. It can disable inoperable proxy servers automatically. Besides, general statistics for total volume of sent and received data, average and current transmission speed is kept. The friendly program interface allows monitoring the proxy servers used, disabling, enabling, and adding new ones in the real-time mode. The user can set proxy server switching criteria himself. These criteria include the number of connections to each proxy server, the time it has been used for, and the volume of data transmitted. Proxy Switch is capable of working with a very great number of simultaneous connections, system resource usage rate being very low. The program is operable under any Windows OS.
