ASP.NET provides a number of ways to maintain user state, the most powerful of which is session state. This article takes an in-depth look at designing and deploying high-performance, scalable, secure session solutions, and presents best practices for both existing and new ASP.NET session state features straight from the ASP.NET feature team.

Hi,I'm looking the article on Session management and Cookie related to ASP.NET MVC.Can somebody please provide links on that topics?
My ASP.NET 1.1 application is using load balancing servers. Before load balancing servers, there is no problem related to session management. After googling, I found the following two points:
1) Website instance ID must be same on both the servers. When I ran Microsoft provided VB Script to check instance ID. On both the servers, they are same.
2) I have also generated a unique machine key and pasted it in the machine.config on both the servers.
Now session does not get expired so frequently. But yes it is happening.
So what should I do next in order to resolve it?
Thanks in advance!

Hi to all,
I have some things that I want to know. I am right now using a free asp.net webhosting ("somee.com"). The problem is that when I am visiting a page, there's a tendency that values stored in my session variables are lost. Therefore, it causes an error when the requested page is loaded.
1. I am thinking of using sessionState mode="SqlServer". Will it solve my problem?
Actualy Im working on it but Im having problems when connecting to the sql database.
2. Is that a problem in the webhost?
3. Do free webhosting sites provide allow session state in the sql server?. Because ive tried it locally into my computer and error say's i should intall the ASP.NET Session State SQL Server version 2.0 or above.
I have a web application in which i need to logout the user if he clicks the logout button or even if he closes his browser window. On Logout button click, i am doing session.Abandon(), but how to go about his browser window close.
Can anybody help with a code sample.
is there any way to find out the reason for session expiry?

I am creating a simple shopping cart using a datatable that is passed into a session object. I have a small mini cart that displays the total number of items in the cart as well as the running total - this is displayed in a web control. When the web control starts up I run a try/catch to see if the session object exists, if it doesn't I create the datatable for the cart and store it in the session. I then have a datalist control that contains all the information for my products including an "add to cart" button. When the page loads everything looks fine. If I click on an "add to cart" button nothing happens to the session information. If I click on it again, the session information updates - displaying only one item is in the cart and then counts up correctly there after. Additionally, after adding an item, if I select a different item in the list, the same issue occurs. I am not sure why this is happeing, if anyone can give me an idea I would appreciate it.

What are the issues (if any) of setting sessions to expire after an extended period of time as in 4-8 hours? I'm building an intranet app which is designed so that users will access it once in the morning and then leave it used, possibly, for hours at a time. I'm assuming that there aren't too many since
1) we're running it on a intranet 2) sessions are soley to retain state between requests3) its not like a connection to the DB where you can conceivable run out
iam insert record using datable in gridivew,iam using session to hold the record,
there is any other way to hold the record in datable.
dtempty.Columns.Add("storeid"); dtempty.Columns.Add("ratetypeid"); dtempty.Columns.Add("ratedesc"); dtempty.Columns.Add("slabs"); dtempty.Columns.Add("days"); dtempty.Columns.Add("rate"); dtempty.Columns.Add("contid"); dtempty.Columns.Add("continertype"); DataRow row; row = dtempty.NewRow(); row["ratetypeid"] = ddlratetype.SelectedValue; row["ratedesc"] = ddlratetype.SelectedItem.Text; row["slabs"] = ddlslabs.SelectedValue; &n
Having a very wierd problem. I have an application that uses Crystal Reports and it uses what I have found to be a common scenario (I am not a CR expert in any way). I have an ASPX page that gathers options for the report, and then it goes and gets the data and if there is some, a button appears for them to launch the report. On clicking that button, the code sets some values in the HttpResponse.Context area, then performs a Server.Transfer to another ASPX page that is our Report Template. This page contains the CR stuff and it generates a PDF version of the report. It then does the following code:
With HttpContext.Current.Response .ClearContent() .ClearHeaders() .ContentType = "application/pdf" .AddHeader("Content-Disposition", "inline; filename=Report.pdf") .BinaryWrite(s.ToArray) .End() E
