DonsProxy HowTo - Basic one-server example

Assume there's a server, google.com, listening on port 80:

We want to set up DonsProxy to listen on 9090, and forward requests to 80:

Also, we'd like to see some of the traffic as it goes by, so we'll start a Subscriber. We could run more than one, and they would all receive the packets as they go by. So, let's run a Subscriber that shows HTTP Headers. Click on the HttpHead tab, and click Start:

Now, hit http://localhost:9090 with your favorite browser:

and you should see something like this:

Now, there's a basic problem here. That is, we can see the first request, but the HTML documents that most sites return include embedded links to other docs and to images, and these all result in additional requests from your browser that will not go to localhost:9090, they'll go right to the host site. So, to see all requests, we need to do something a little more advanced.
