From Proxy Labs
ProxyCap enables you to redirect applications through a SOCKS or HTTP proxy server. You can tell ProxyCap which applications will connect to the Internet through a proxy and under what circumstances. This is done through a user friendly interface, without the need to reconfigure any of your Internet clients. ProxyCap provides flexible rule system and allows you to define your own routing rules. You can add a new rule with just a few mouse clicks.
This release adds the ability to specify a SSH server as the proxy server, makes routing rules even more flexible.
