"""

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
