|request-id||Optional. Request id to include in log messages sent by JSNLog to the server. See remarks.|
This can only be used in ASP.NET Core web applications.
JSNLog gets the request id of the request, or if it can't, generates its own unique id. It sends that with all log messages to the server so log messages belonging to the same request can be correlated (details).
If however you generate your own request ids and you want JSNLog to use that instead, pass in your request id.
