Hello, I've found a way how to test websockets automatically. this approach is able to catch https://github.com/haproxy/haproxy/issues/737
the idea is to place haproxy between browser and kestrel in SignalR tests ( https://github.com/dotnet/aspnetcore/tree/main/src/SignalR ) test takes 3 hours on my low end laptop. I collected all required parts in https://github.com/chipitsine/haproxy-signalr-tests also, I checked current maintained branches, no issues (last issue was fixed in issue 737). cheers, Ilya
