Your question is valid. You are probably mostly thinking of web facing web servers. Serving HTML (or json or websockets) can be used for so much more. I use Nancy instead of IIS because I have a small application that I only want to reach from the inside while IIS is outward facing. Also – … Read more
The UseOAuthBearerTokens extension method creates both the token server and the middleware to validate tokens for requests in the same application. Pseudocode from source using reflector: UseOAuthAuthorizationServer(); // authorization server middleware UseOAuthBearerAuthentication(ApplicationOAuthBearerProvider); // application bearer token middleware UseOAuthBearerAuthentication(ExternalOAuthBearerProvider); // external bearer token middleware
CreatePerOwinContext registers a static callback which your application will use to get back a new instance of a specified type. This callback will be called once per request and will store the object/objects in OwinContext so that you will be able to use them throughout the application. Let’s say you have defined your own implementation … Read more
Katana is Microsoft’s OWIN implementation and also includes some middleware components for security/authentication, serving static files, and a few other things. Kestrel is Microsoft’s cross-platform development web server that can be used with ASP.NET 5. ASP.NET 5 does not implement OWIN, but has a “bridge” to enable OWIN components to be used in ASP.NET 5 … Read more
I have encountered the same problem and traced the cause to OWIN ASP.NET hosting implementation. I would say it’s a bug. Some background My findings are based on these assembly versions: Microsoft.Owin, Version=2.0.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 Microsoft.Owin.Host.SystemWeb, Version=2.0.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a OWIN uses it’s own abstraction to work with response Cookies (Microsoft.Owin.ResponseCookieCollection). This … Read more
In asp.net WebApi v2, the OWIN pipeline becomes the default. It is eventually going to be the standard pipeline under any asp.net project. I cannot put it better than what is written here : http://www.asp.net/aspnet/overview/owin-and-katana/an-overview-of-project-katana The section “The Open Web Interface for .NET (OWIN)” explains perfectly the goals of OWIN. Without OWIN, the asp.net bits … Read more
Regarding the comment above, OWIN is not a framework. OWIN is a specification on how web servers and web applications should be built in order to decouple them and allow movement of ASP.NET applications to environments which were not supported before. Prior to OWIN, when building ASP.NET application, you were inherently bound to IIS due … Read more
