Hi! I was experimenting with sending WebSocket requests using libcurl. Since my codebase already uses the callback approach for HTTP requests and I was just adding support for WebSocket connections, I thought of continuing using the same write callback for WebSocket connections too. However, I was trying to connect with a WebSocket server that expects the client to send data before responding. So I had a question:
When using the callback approach <https://everything.curl.dev/libcurl/ws/concept#1.-the-callback-approach>, is it possible to run curl_ws_send() right after the connection is established, before the write callback function is executed for the first time? It isn't documented but I still tried setting CURLOPT_READFUNCTION to a valid read callback function but that didn't work, so I guess read callbacks are not expected to work when doing WebSocket requests. Does this mean that I would need to use the connect-only approach <https://everything.curl.dev/libcurl/ws/concept#2.-the-connect-only-approach> for WebSocket connections? Even if we find a solution for the callback approach, I was wondering if any of these approaches <https://everything.curl.dev/libcurl/ws/concept> are recommended over the other? Thanks!
