The ping
method of Microsoft's SignalR library seems to attach a random number to the URL it calls. This leads to an error 400: "A potentially dangerous Request.Path value was detected from the client".
The auto-generated URL is: https://myProject.url/signalr/signalr/ping&_=1643826682616
Is there a way to prevent SignalR from attaching this random number? Or have I missed any required setting?
The solution was to update my client-side npm package signalr-asp-net
. I still had version 1.0.0 and updated to 1.0.3.
