Proxy server that fully supports all the following protocols: HTTP, HTTP CONNECT (for HTTPS and so on), SOCKS4 (TCP and TCP bind) and SOCKS5 (TCP, TCP bind and UDP). It's designed to be small and for being used in trusted environments where there is no need of complex or advanced options and other boring things, double click on it and it will work immediately. It supports also some options like binding a specific interfaces for incoming or outgoing connections, custom port to bind (default is 8123), stdout and file verbose logging.
the tool works also as a Windows service. Please note that this tool is not good for production, the problem resides in the DNS caching mechanism which is not perfect; you can disable it with the -D function that hopefully would rely on the caching of the OS.
