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

public void SaveSessionID(
	HttpContext context,
	string id,
	out bool redirected,
	out bool cookieAdded


Type: System.Web.HttpContext

The current HttpContext object that references server objects used to process HTTP requests (for example, the Request and Response properties).

Type: System.String

The session identifier.

Type: System.Boolean

When this method returns, contains a Boolean value that is true if the response is redirected to the current URL with the session identifier added to the URL; otherwise, false.

Type: System.Boolean

When this method returns, contains a Boolean value that is true if a cookie has been added to the HTTP response; otherwise, false.

Exception Condition

The response has already been sent.


The session ID passed to this method failed validation.

This method is not intended to be called from application code.

The SaveSessionID method is called by the SessionStateModule object during the AcquireRequestState event. The SaveSessionID method stores the session identifier in either the URL (when cookieless session state is used) or in a non-expiring session cookie.

By default, the SessionIDManager places a unique session identifier into a non-expiring session cookie and sets the cookieAdded parameter to true.

For a cookieless session state, the SessionIDManager object inserts a unique session identifier into the current URL, redirects the browser to the new URL that includes the session identifier, and then sets the redirected parameter to true.
