This interface should be implemented by a custom HttpHandler. This
interface contains no members and is used only as a marker. When
present, it tells ASP.NET that the HttpHandler should be given read
and write access to the HttpSessionState
collection.
Every HttpHandler should implement either
IReadOnlySessionState or
IRequiresSessionState, or session state variables
will not be accessible.
public interface IRequiresSessionState {
// No public or protected members
}
