  • (2020-07-01, v:1.0.0) Ian Goodwin: sub protocol
    Is it possible to set the sub protocol?
  • (2020-06-16, v:1.0.0) vivanraj k: Hi Kindly suggest how to frame the socket address
    I want to run my socket in local. kindly guide me how to form the socket address
  • (2019-08-08, v:1.0.0) Client stopped receiving events from server if left idle for some time.
    It is working good. However, if left idle for some time it stops receiving any events from server though latter is continuously sending them. Also, as per the protocol of web sockets client don't need to poll server for keeping the connection alive. Right?
  • (2019-01-15, v:1.0.0) W. E.: Do you have an instruction set or manual on how to use this?
    I got a localhost, but I don't know how to set up username, type message, etc. Is there a manual for this?
  • (2018-11-19, v:1.0.0) Cookies
    Is it possible to pass cookies with wss URL?
  • (2018-06-16, v:1.0.0) Tony Kenny: Cannot connect & no message
    I cannot connect to a websocket, probably a problem with the socket, but this app does not give any feedback, doesn't even tell me the connection failed until I try to send data.
  • (2016-07-22, v:1.0.0) Krupal Maddipati: The history section isn't clickable
    I really love SWC but one thing I can't figure out is why doesn't the history section show the request/response data for prev requests.
