Redirection après l'expiration de session

If Not Context.Session Is Nothing Then 'Tested and the IsNewSession is more advanced then simply checking if ' a cookie is present, it does take into account a session timeout, because ' I tested a timeout and it did show as a new session If Session.IsNewSession Then ' If it says it is a new session, but an existing cookie exists, then it must ' have timed out (can't use the cookie collection because even on first ' request it already contains the cookie (request and response ' seem to share the collection) Dim szCookieHeader As String = Request.Headers("Cookie") If (Not szCookieHeader Is Nothing) And (szCookieHeader.IndexOf("ASP.NET_SessionId") >= 0) Then Response.Redirect("sessionTimeout.htm") End If End If End If

C bon, c'est résolu :mouarf:

Alors la solution consiste à rajouter une balise Meta d'information.
Cette balise c'est Refresh. Elle oblige le navigateur à rafraîchir la page au bout d'un temps donné (en seconde). Après rafraichessement, je teste si la session a expiré, si c'est le cas, je fais la redirection.

Je l'ai rajouté au niveau du code. Vous pouvez la mettre directement dans le code HTML. Voici la solution :

Response.AddHeader("Refresh", Convert.ToString((Session.Timeout * 60) + 5))
 
            If Not Context.Session Is Nothing Then
 
                'Tested and the IsNewSession is more advanced then simply checking if 
                ' a cookie is present, it does take into account a session timeout, because 
                ' I tested a timeout and it did show as a new session
                If Session.IsNewSession Then
                    ' If it says it is a new session, but an existing cookie exists, then it must 
                    ' have timed out (can't use the cookie collection because even on first 
                    ' request it already contains the cookie (request and response
                    ' seem to share the collection)
                    Dim szCookieHeader As String = Request.Headers("Cookie")
                    If (Not szCookieHeader Is Nothing) And (szCookieHeader.IndexOf("ASP.NET_SessionId") >= 0) Then
                        ' Log User Off from Cookie Authentication System
                        FormsAuthentication.SignOut()
                        ' Invalidate roles token
                        Response.Cookies("portalroles").Value = Nothing
                        Response.Cookies("portalroles").Path = "/"
                        Response.Cookies("portalroles").Expires = New System.DateTime(1999, 10, 12)
                        ' Redirecton vers la page 
                        Response.Redirect("~/Admin/AccessDenied.aspx")
                    End If
                End If
            End If

Voila, j'espère que cette solution va vous aider. A bientot :yaisse2:
