Почему вместо параметра Conection HttpContext'а выводится Keep-Alive

class Person
{
    public void App()
    {
        var builder = WebApplication.CreateBuilder();
        var app = builder.Build();

        app.MapGet("/", (HttpContext context) =>
        {
            var requests = context.Request.Headers;

            context.Response.WriteAsync(requests.Connection);
        });

        app.Run();
    }
}

class Programm
{
    static void Main()
    {
        Console.Write("Ае");

        Person person1 = new Person();
        person1.App();
    }
}
