Transparent Proxying
|
|
====================
|
|
|
|
When a transparent proxy is used, traffic is redirected into a proxy at the
|
|
network layer, without any client configuration being required. 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_ on Linux
|
|
or pf_ 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.
