Setup Windows SSH to connect via Proxy to Host

I had the problem to connect to a SSH Host through a HTTP Proxy. I could run it with Putty, just entering the host and port in the proxy configuration section.

Fine so far, but I want to clone GIT repositories from this host, git clone ssh://foo@host.org. So Putty was out (maybe I could tunnel…). So I used this solution:

• Install basic Cygwin
• Install packages openssh, git and corkscrew
• Setup  ~/.ssh/config (where 10.10.10.10 is the HTTP proxy host and 8080 the http proxy port.

Host host.org
    ProxyCommand corkscrew 10.10.10.10 8080 %h %p

That was all, I setup my SSH key and could connect.
