This makes transparent proxying ideal for those situations +where you can't change client behaviour - proxy-oblivious Android applications being a common +example. +To set up transparent proxying, we need two new components. The first is a +redirection mechanism that transparently reroutes a TCP connection destined for +a server on the Internet to a listening proxy server. This usually takes the +form of a firewall on the same host as the proxy server - +[iptables](http://www.netfilter.org/) on Linux or +[pf](http://en.wikipedia.org/wiki/PF_\(firewall\)) on OSX. When the proxy receives a redirected connection, it sees a vanilla HTTP request, without a host specification. This is where the second new component comes in - a host module that allows us to query the redirector for the original destination of the TCP connection. + +At the moment, mitmproxy supports transparent proxying on OSX Lion and above, and all current flavors of Linux.kkkkk \ No newline at end of file -- cgit v1.2.3
