"""
Process individual messages from a TCP connection.
This script replaces full occurences of "foo" with "bar" and prints various details for each message.
Please note that TCP is stream-based and *not* message-based. mitmproxy splits stream contents into "messages"
as they are received by socket.recv(). This is pretty arbitrary and should not be relied on.
However, it is sometimes good enough as a quick hack.
Example Invocation:
mitmdump --rawtcp --tcp-hosts ".*" -s examples/tcp-simple.py
