IReadOnlySessionState Interface

Specifies that the target HTTP handler requires only read 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)

Syntax

Visual Basic (Declaration)

<AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level := AspNetHostingPermissionLevel.Minimal)> _
<AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level := AspNetHostingPermissionLevel.Minimal)> _
Public Interface IReadOnlySessionState _
    Inherits IRequiresSessionState

Visual Basic (Usage)

Dim instance As IReadOnlySessionState

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

Visual C++

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

JScript

public interface IReadOnlySessionState extends IRequiresSessionState

Remarks

Implement the IReadOnlySessionState interface in your custom handler to identify that your handler requires only read access to session-state values.

Examples

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

Visual Basic

Dim readOnlySession As Boolean = False

If TypeOf (Context.Handler) Is IReadOnlySessionState Then
  readOnlySession = True
End If

bool readOnlySession = false;

if (Context.Handler is IReadOnlySessionState)
  readOnlySession = true;
