A mitmproxy script that blocks and removes well known Matrix server
|
||
|
|
information.
|
||
|
|
|
||
|
|
There are two ways a Matrix server can trigger the client to reconfigure the
|
||
|
|
homeserver URL:
|
||
|
|
|
||
|
|
1. By responding to a `./well-known/matrix/client` request with a new
|
||
|
|
homeserver URL.
|
||
|
|
|
||
|
|
2. By including a new homeserver URL inside the `/login` response.
|
||
|
|
|
||
|
|
To run execute it with mitmproxy:
|
||
|
|
|
||
|
|
>>> mitmproxy -s well-known-block.py`
|
||
|
|
|
||
|
|
