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

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

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

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

bool readOnlySession = false;

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