Output caching middleware must implement IMiddleware<IOutputCache> to signal to the pipeline builder that it provides an output caching mechanism. Any middleware that specifies .RunAfter<IOutputCache>() will be added to the OWIN pipeline after the middleware that implements IMiddleware<IOutputCache> ensuring that the output caching mechanism is available to middleware that depends on it.

The methods and properties of the IOutputCache interface are fully described in the XML documentation comments. Please use the Intellisense system in Visual Studio to access this documentation.
