I just want simple login and after session expire supoose after 1 min the page will redirect automatically to login page and asking for sign in again.
At the time of successfull login create a session and pass a unique value to the session.and on other pages pageload check the same session whether its null or empty or not.If its not null then user is currently logged in so let them access the page else
redirect them to login page and destrory the sessions.
Assign unique key to session:
Session["user"]=Convert.ToString(Guid.NewGuid());
Check the session after successful login on other pages pageload.
if(Session["user"] != null || Session["user"] != string.Empty)
{
// let him access the page
}
else
{
//clear the cache and redirect back to login page.
Response.Redirect("LoginPage.aspx");
}
actually i have stored user name in session ...because user name is redirected to net page with welcome user name status.
This is good .. you can proceed like this.

so i need to store unique key in differnt session?
Yes.For each session there should be a unique key or value that differentiate that user from other apart from your username session.so check both the sessions in every page load.A better approach would be using forms authentication.
SqlCommand cm =new SqlCommand("Select * FROM login WHERE name=@name and password=@password",cn);
cm.Parameters.Add("@name", SqlDbType.VarChar).Value = name;
cm.Parameters.Add("@password", SqlDbType.VarChar).Value = password;
Forget the idea of redirecting when the session times out, the web doesn't support that kind of feature. My session might have timed out because I'm viewing a different site or I've shut my pc down. It's possible but a) very annoying for users as they
might want to keep your page in their browser to view it at their leisure b) involves a semi-advanced solution.

I'm afraid I no longer use this forum due to the new point allocation system.
the page will not automatically redirect back to login page.you have to make a refresh or postback to hit it server then only you will be able to see the changes.just make sure you have session timeout set in web.config for this.

Hi,
You can try with refresh meta tag, where content= session timeout in seconds.
Check this site for info:

Hello,
To set session timeout you can set it from web.config.
<configuration> <system.web> <sessionState timeout="10"></sessionState> </system.web> </configuration>At the time of successfull login create a session and pass a unique value to the session.and on other pages pageload check the same session whether its null or empty or not.If its not null then user is currently logged in so let them access the page else redirect them to login page and destrory the sessions.
Assign unique key to session:
Check the session after successful login on other pages pageload.
if(Session["user"] != null || Session["user"] != string.Empty) { // let him access the page } else { //clear the cache and redirect back to login page. Response.Redirect("LoginPage.aspx"); }Hope It Helped. :)
