Examples

Run wstcp in a terminal:

Apr 22 23:21:20.717 INFO Starts a WebSocket proxy server, server_addr: 127.0.0.1:3000, proxy_addr: 0.0.0.0:13892

Run a TCP server (in this example nc is used) in another terminal:

$ nc -l 127.0.0.1 -p 3000

Use ws to launch a WebSocket client:

$ ws ws://localhost:13892/
> foo # Enter "foo" and press the Enter key

After this, the "foo" string is displayed on the terminal running nc.
