Syntax
Remarks
The System.Web.SessionState.SessionStateUtility class provides static helper methods that are used by a session-state module or a session-state store provider. Application developers will not need to call these methods from their code.
The following table describes the ways the session-state module and session-state store provider use the methods.
| SessionStateUtility.GetHttpSessionStateFromContext(System.Web.HttpContext) method |
Can be used by custom session-state modules to either retrieve session information for an existing session or create session information for a new session. |
| SessionStateUtility.AddHttpSessionStateToContext(System.Web.HttpContext, IHttpSessionState) method |
Called by the session-state module to add the session data to the current System.Web.HttpContext and make it available to application code through the System.Web.HttpContext.Session property. |
| SessionStateUtility.RemoveHttpSessionStateFromContext(System.Web.HttpContext) method |
Called by the session-state module during the System.Web.HttpApplication.ReleaseRequestState or System.Web.HttpApplication.EndRequest events at the end of a request, to clear session data from the current System.Web.HttpContext. |
| SessionStateUtility.GetSessionStaticObjects(System.Web.HttpContext) method |
Called by the session-state module to get a reference to the HttpSessionState.StaticObjects collection based on objects defined in the Global.asax file. The System.Web.HttpStaticObjectsCollection collection returned is included with the session data added to the current System.Web.HttpContext. |
Session data is passed to and retrieved from the current System.Web.HttpContext as an System.Web.SessionState.HttpSessionStateContainer object or any valid implementation of the System.Web.SessionState.IHttpSessionState interface.
