bauglir sending duplicate headers? lazarus / 38-Networking and Web Programming ---------------------------------------------------------------------- Trenatos · 2017-09-07 13:50 I'm trying to get bauglir running, I changed inherited according to this thread http://forum.lazarus.freepascal.org/index.php?topic=30649.0 I grabbed the Lazarus demo, and it starts up fine, but when I try to connect using the demo page, I get an error claiming "Error during WebSocket handshake: 'Sec-WebSocket-Protocol' header must not appear more than once in a response" but when I inspect the request, I only see the one header. Has anyone run into this before? ---------------------------------------------------------------------- Trenatos · 2017-09-07 13:52 I just changed the demo to read socket = new WebSocket(scheme + host + ':' + port, ['proto1']); (I remove proto2 from the array) and now I'm getting another error. "Error in permessage-deflate: client_max_window_bits must have value". Going to keep trying, but if someone has solved this stuff already I'd love to hear about it ---------------------------------------------------------------------- Trenatos · 2017-09-07 13:56 AHA! It's a Chrome issue. Works fine in FireFox.
