Hello, we establish a WebSocket connection using libcurl (7.61.0) (easy interface). With activated logging, schannel (Windows) is logging many thousand entries like this:

Does that simply mean it waits for data on this channel/connection or does it mean there is some activity? Is it normal to have that on WebSocket connections? Or are we doing it wrong somewhere? On Linux, there are no such messages in the logfiles for WebSocket connections. With the same code basis for our product but, of course, not schannel.
