This is a test-client for the transit-relay that uses WebSockets.
|
|
|
|
If an additional command-line argument (anything) is added, it will
|
|
send 5 messages upon connection. Otherwise, it just prints out what is
|
|
received. Uses a fixed token of 64 'a' characters. Always connects on
|
|
localhost:4002
