Passing parameters from middleware to controller - asp.net core

I need to pass some parameters from middleware to controller and I'm confused which approach should I use if I have to take care of performance, resource usage and security.

(It is the requirement to keep the Session enabled anyway.)

You could pass it as an http header down the pipeline with the request

public class UserHeaderMiddleware  
{
    private readonly RequestDelegate _next;

    public UserHeaderMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        context.Request.Headers.Add("user-id", new[] { userId.ToString() });
        await _next(context);
    }
}

If you need to store the user ID for the future, session is the way to go. Items only passes it along for that request.
