Dear All,

I have 3 users on my site and each one of them when sign out it redirects to a different page.

how can i handle this when session time out???

Example:

Factory User:
* Stores credentials in session["FactoryInfo"];
* redirects to login.aspx

Admin User:
* Stores its credentials in session["AdminUser"];
* redirects to adminlogin.aspx

Normal User:
* Stores its credentials in session["NormalUser"];
* redirects to homelogin.aspx

No if user presses on logout link it redirects each user to its login page based on its session variable.

C#

if (Session["FactoryInfo"] != null)//Factory User
{
    Session.Clear();
    Response.Redirect("login.aspx");
}
else if (Session["AdminUser"] != null)//Admin User
{                
    Session.Clear();
    Response.Redirect("adminlogin.aspx");
}
else if(Session["NormalUser"] != null)//Normal User
{
    Session.Clear();
    Response.Redirect("homelogin.aspx");
}

Now if the session times out, then all session variables are NULL!!
so how can i detect the current user and redirects to its specific login page?!!!

Actually i did that solution but i faced a problem.
I am setting the hiddenfield when the user login to the system with its type but it didn't keep the value and after it redirects to its page, it looses its value.
Do you have any idea???

Do the thing like this . i think u are setting the hiddenfield value above the redirection code . im i right? . if yes , then put that below the rediection code . hope u will get the solution .. best of luck .

yes i am setting the hiddenfield value before response.redirect but if i did that after response.redirect, this code will be unreachable.
Am i Right??

set the hiddenfiel value like this on the master page

protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{

if (Session["FactoryInfo"] == null || Session["AdminUser"] == null || Session["NormalUser"] == null)
{
//if u will get any of the session time out .. than break to below the code of setting HiddenField value .. it will not reset the hidden field value.
goto switchHere;
}
else
{
if (Session["FactoryInfo"] != null)
HiddenField1.value = Session["FactoryInfo"].tostring();
if (Session["AdminUser"] != null)
HiddenField1.value = Session["AdminUser"].tostring();
if (Session["NormalUser"] != null)
HiddenField1.value = Session["NormalUser"].tostring();

}

switchHere:
if (Session["FactoryInfo"] == null || Session["AdminUser"] == null || Session["NormalUser"] == null)
{
if (HiddenField1.value=="FactoryInfo")//Factory User
{
Session.Clear();
Response.Redirect("login.aspx");
}
else if (HiddenField1.value=="AdminUser")//Admin User
{
Session.Clear();
Response.Redirect("adminlogin.aspx");
}
else if(HiddenField1.value=="NormalUser")//Normal User
{
Session.Clear();
Response.Redirect("homelogin.aspx");
}
}

}
}

and on the logout button ... if session not expired .. then u have to redirect based on session... and if timeout stuck... than u have to redirect based on hiddenfield value

I appreciate your answer so much..

Ashutosh shukla207 28-Dec-15 1:53am

try this . it will work.. best of luck.

thanks i found my own solution which is:
In the redirected page i am inheriting a custom class that inherits from System.Web.Ui.Page and in the page_init event i am setting the hidden field value based on the session variables.
That worked for me very good.
but your answer was the entry point for me.
Thanks....
