+Client playback: a 30 second example
+====================================
+
+My local cafe is serviced by a rickety and unreliable wireless network,
+generously sponsored with ratepayers' money by our city council. After
+connecting, you  are redirected to an SSL-protected page that prompts you for a
+username and password. Once you've entered your details, you are free to enjoy
+the intermittent dropouts, treacle-like speeds and incorrectly configured
+transparent proxy.
+
+I tend to automate this kind of thing at the first opportunity, on the theory
+that time spent now will be more than made up in the long run. In this case, I
+might use Firebug_ to ferret out the form post
+parameters and target URL, then fire up an editor to write a little script
+using Python's urllib_ to simulate a submission.
+That's a lot of futzing about. With mitmproxy we can do the job
+in literally 30 seconds, without having to worry about any of the details.
+Here's how.
+
+1. Run mitmdump to record our HTTP conversation to a file.
+----------------------------------------------------------
+
+>>> mitmdump -w wireless-login
+
+2. Point your browser at the mitmdump instance.
+-----------------------------------------------
+
+I use a tiny Firefox addon called `Toggle Proxy`_ to switch quickly to and from mitmproxy.
+I'm assuming you've already :ref:`configured
+your browser with mitmproxy's SSL certificate
+authority <certinstall>`.
+
+3. Log in as usual.
+-------------------
+
+And that's it! You now have a serialized version of the login process in the
+file wireless-login, and you can replay it at any time like this:
+
+>>> mitmdump -c wireless-login
+
+Embellishments
+--------------
+
+We're really done at this point, but there are a couple of embellishments we
+could make if we wanted. I use wicd_ to
+automatically join wireless networks I frequent, and it lets me specify a
+command to run after connecting. I used the client replay command above and
+voila! - totally hands-free wireless network startup.
+
+We might also want to prune requests that download CSS, JS, images and so
+forth. These add only a few moments to the time it takes to replay, but they're
+not really needed and I somehow feel compelled to trim them anyway. So, we fire up
+the mitmproxy console tool on our serialized conversation, like so:
+
+>>> mitmproxy -r wireless-login
+
+We can now go through and manually delete (using the :kbd:`d` keyboard shortcut)
+everything we want to trim. When we're done, we use :kbd:`w` to save the
+conversation back to the file.
