Data caching per request in Owin application

Question

In traditional ASP.NET applications (that use System.Web), I\'m able to cache data in

HttpContext.Current.Items 

Now in Owin the HttpConte

Answer 1

You just need to use OwinContext for this:

From your middleware:

public class HelloWorldMiddleware : OwinMiddleware
{
   public HelloWorldMiddleware (OwinMiddleware next) : base(next) { }

   public override async Task Invoke(IOwinContext context)
   {   
       context.Set("Hello", "World");
       await Next.Invoke(context);     
   }   
}

From MVC or WebApi:

Request.GetOwinContext().Get<string>("Hello");

Answer 2

Finally I found OwinRequestScopeContext. Very simple to use.

In the Startup class:

app.UseRequestScopeContext();

Then I can add per request cache like this:

OwinRequestScopeContext.Current.Items["myclient"] = new Client();

Then anywhere in my code I can do (just like HttpContext.Current):

var currentClient = OwinRequestScopeContext.Current.Items["myclient"] as Client;

Here is the source code if you're curious. It uses CallContext.LogicalGetData and LogicalSetData. Does any one see any problem with this approach of caching request data?
