Public Interface IRequiresSessionState

Visual Basic (Usage)

Dim instance As IRequiresSessionState

[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public interface IRequiresSessionState

Visual C++

[AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)]
public interface class IRequiresSessionState

JScript

public interface IRequiresSessionState

Remarks

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

Examples

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

Visual Basic

Dim requiresSession As Boolean = False

If TypeOf (Context.Handler) Is IRequiresSessionState Then
  requiresSession = True
End If

bool requiresSession = false;

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