Login control with sessions

Hello every one,

I am new in asp.net development.
I am doing project in asp.net with vb.
I am using inbuilt login control and created sessions. Some times sessions works but sometimes gives errors. specially when I log out and login back in system. Also not able to clear sessions whil logging out the system.

Please help me.

HI ! i give you one example with coding i hope it will help you.


public class BasePage : System.Web.UI.Page
{
public SecurityApplicationPageBase()
{
this.Load += new System.EventHandler(this.Page_Load);
}

private void Page_Load(object sender, System.EventArgs e)
{

if(Session["Session_name"]==null)
{
Response.Redirect("Login.aspx");
}
InjectSessionExpireScript();
}

// For demo purpose the timeout is set to a smaller value.
//Remember The Javascript setTimeout works in milliseconds.
protected void InjectSessionExpireScript( )
{
string script = "<script> \n" +
"function expireSession(){ \n"+
" window.location = '"+"Logout.aspx"+"'}\n"+
"setTimeout('expireSession()', " +this.Session.Timeout * 1000 +" ); \n"+
"</script>"
this.Page.RegisterClientScriptBlock("expirescript",script);
}
}

Logout Page: This page calls Session.Abandon() and redirects to the login.aspx page.

public class LogOut : BasePage
{
private void Page_Load(object sender, System.EventArgs e)
{
Session.Abandon();
Response.Redirect("Login.aspx",true);
}
}

Login Page: This page facilitates login. On a successful login a Session variable is created.


public class LogIn : System.Web.UI.Page
{

private void btnLogin_Click(object sender, System.EventArgs e)
{
//when username and pasword is correct
Session.Add("Session_name","loggedinsuccessfully");
}
}

You may face some issues while using the inbuilt login control by Asp.net. Try your own custom built login control.
