Following standard online directions, I set up an ssh tunnel at home using putty to access private web pages accessible only on my work network. Fortunately, this just worked; when I sshed into a machine on our private network with the tunneling options set in putty, and set my browser to use the corresponding port on localhost, I could access web pages on our private network.
I am curious how this typically works on the server side. Did someone already set up a proxy server in addition to the ssh server? The following question seems to suggest that this is unnecessary, and that the ssh server already supports http proxy requests: Do I need to have a proxy server to have HTTP over SSH?
How I can investigate on my own to see which http proxy server my traffic is going through?
