I'm in the process of converting my ASP.NET Web API from being IIS hosted to being self hosted.
In one of my DelegatingHandlers I set the current user based on the token from the HTTP header. I've been using HttpContext.Current.Items to store this information, but that isn't available under self hosting.
What is the correct way to store per request data that can be accessed anywhere in my application?
The Request message has a Properties collection.
