FreeCap is a free program that allows you to forward connections through a SOCKS server. The application injects a DLL into the programs it launches, intercepts their Winsock API calls and redirects connection requests. Given the fact that not all programs are able to work directly through SOCKS-proxies (e.g. Internet Explorer), FreeCap will be extremely useful for performing the required operations. It supports SOCKS 4 and 5, chains of proxy servers and tunneling through HTTP proxies. FreeCap is open source under the GNU GPL and no longer developed.
FreeCap allows forwarding connections through a SOCKS server, making it possible to use programs that don't support SOCKS-proxies directly.
