Request Features

ASP.NET Core defines a number of HTTP feature interfaces in Microsoft.AspNetCore.Http.Features which are used by servers to identify the features they support. The following feature interfaces handle requests and return responses:

• IHttpRequestFeature Defines the structure of an HTTP request, including the protocol, path, query string, headers, and body.

• IHttpResponseFeature Defines the structure of an HTTP response, including the status code, headers, and body of the response.

• IHttpAuthenticationFeature Defines support for identifying users based on a ClaimsPrincipal and specifying an authentication handler.

• IHttpUpgradeFeature Defines support for HTTP Upgrades, which allow the client to specify which additional protocols it would like to use if the server wishes to switch protocols.

• IHttpBufferingFeature Defines methods for disabling buffering of requests and/or responses.

• IHttpConnectionFeature Defines properties for local and remote addresses and ports.

• IHttpRequestLifetimeFeature Defines support for aborting connections, or detecting if a request has been terminated prematurely, such as by a client disconnect.

• IHttpSendFileFeature Defines a method for sending files asynchronously.

• IHttpWebSocketFeature Defines an API for supporting web sockets.

• IHttpRequestIdentifierFeature Adds a property that can be implemented to uniquely identify requests.

• ISessionFeature Defines ISessionFactory and ISession abstractions for supporting user sessions.

• ITlsConnectionFeature Defines an API for retrieving client certificates.

• ITlsTokenBindingFeature Defines methods for working with TLS token binding parameters.
