Hi team, are we able to change the header value at runtime for WebSocket client? I tried this, but it didn't work well. Any thoughts?

suspend fun create(
    path: String,
    isDebug: Boolean,
    session: suspend DefaultClientWebSocketSession.() -> Unit
) {
    ktorClient.config {
        defaultRequest {
            header("x-debug-request", isDebug)
        }
    }.wss(
        method = HttpMethod.Get,
        host = "...",
        path = path,
        block = session
    )
}

Updated:
TIL; once the ws connection is established, we cannot change the request header. But is there any way to do so without closing and reopening the ws connection?

Thanks!

There are no headers on Websocket connections after the connection is established.
The flow for a WS connection is:
• HTTP ‘upgrade’ request (this is an HTTP request, you can add headers here);
• Websocket connection established; this is now whatever protocol you’ve chose to use on the WS connection (perhaps that supports the concept of “headers”?)

Can you explain why you need to change the header value at runtime?
