Both HTTP and SSH are application level transports,  however both can be 
used to tunnel TCP connections.  Therefore it is possible to use ssh 
over http.  The windows putty client can use http proxies to make 
outbound connections as long as your http proxy is configured to allow 
CONNECT requests to port 22.  If you using squid for example with a 
defaultish config you will need to update your proxy server configuration.
