Inside Application_PostAcquireRequestState method, Context.GetRequestTelemetry() method always returns null value RRS feed

  • Question

  • Integrating AppInsights to ASP.NET MVC application. Want to send authenticated user id information to the app insights.

    Followed the steps mentioned in the below link.

    protected void Application_PostAcquireRequestState() { var requestTelemetry = Context.GetRequestTelemetry(); if (HttpContext.Current.Session != null && requestTelemetry != null && string.IsNullOrEmpty(requestTelemetry.Context.User.Id)) { requestTelemetry.Context.User.Id = Session.SessionID; } }

    Context.GetRequestTelemetry() method in the above method always returns null.

    Any suggestions ?

  • Hello, Mahendra!

    By default, web apps identify users by using cookies.  A new ASP.NET MVC application will give you something like this when you run it:


    That long line of text will include something like the following:":"abc4e"


    For authenticated users, you'll need to follow our documentation here:


    Which will include code that may look like this:

    @if (Request.IsAuthenticated)
                .Replace("\\", "\\\\")"
                .replace(/[,;=| ]+/g, "_"));

    Don't forget that in your project in Visual Studio, you have "Connected Services" that will allow you to configure authentication with Azure Active Directory if you haven't already done so.
