I am wondering how OLS manages the 'Connection: Keep-Alive' header. I had added it to my custom headers and it was causing issues with HTTP/2, so I removed it. But I still see it reappear by itself:
Is that something OLS could insert by itself based on settings?
http2 error: Invalid HTTP header field was received: frame type: 1, stream: 1, name: [connection], value: [Keep-Alive]
