WebSockets enable the server and client to send messages to each other at any time, after a connection is established, without an explicit request by one or the other. This is in contrast to HTTP, which is traditionally associated with the challenge-response principle — where to get data one has to explicitly request it.
Install instructions (Windows) - Using the installer (recommended) : download it, launch it and follow the instructions. - Using the .zip archive : copy the contents of the archive to the root of your OBS Studio installation folder. Particularly, when HttpsServer based project is compiled with Java v11.0.7+8-LTS, and FireFox Dev 87.0b3 connects with JS WebSocket object - the pool thread hangs and every other websocket connection will cause backlog fill up adding about 6% on CPU load on my PC on each F5 page refresh.
