Hello. When i tried to write WebSocket server on gawk i've got one trouble. WebSocket connection setting up after handshake (http header) and after that host and client exchange data by sending dataframes. So i can make handshake and send frames from host to client (browser), but cannot receive it. I saw TCP-packet from client to host, but construction "host |& getline packet" cannot receive that (following by getline code isnt executed) Code on github: https://github.com/MagistrZoom/AWK/blob/master/server . If it is not a bug, can you tell me, how i can fix that?
