IRequiresSessionState Interface

Specifies that the target HTTP handler requires read and write access to session-state values. This is a marker interface and has no methods.

Namespace:  System.Web.SessionState
Assembly:  System.Web (in System.Web.dll)

public interface IRequiresSessionState

Implement the IRequiresSessionState interface in your custom HTTP handler to identify that your handler requires read and write access to session-state values.

The following code example examines the current HTTP Handler property to determine whether it requires read and write access to session-state values.


bool requiresSession = false;

if (Context.Handler is IRequiresSessionState)
  requiresSession = true;
