State Management :: SQL Session State Lost After Close Browser?

May 3, 2010

I'm not sure if this is an error or is the right work mode for sql sessions.

I'm working now with Windows 2008 R2 Web Ed. and SQL Server 2008 Web Ed.

When I close my browse and open again a new browser window I need to login again in application and a new session is created in the sessions table in sql server.

It's this normal? I remember that with Windows 2003 and SQL 2005 this doesn't happend. When I closed my browser and open inmediately a new browser window my session was retained and I could continue working without relogin.

State Management :: Session State Variables Getting Lost?

Jun 28, 2010

I am working on an website using C#. The site deals with orders and therefore order lines. I would like to store the order in memory whilst it is being populated (with order lines) and once it gets submitted write it to a database.

The above logic has been implemented, but sometimes when accessing session state or storing a variable in it information gets lost. Take note that the web server is running a dual-core processor. I am also using the in proc session state server.

I tried changing over to using the out proc session state server ( state service), but it requires serialization. Since the order and orderlines are actually linq to sql classes, the entitysets and entityref's fail to serialize.

Does anyone know the reason why session state loses information occasionally and possibly how to eliminate the problem?

State Management :: Session State Gets Lost?

Dec 16, 2010

I have a problem with a couple of web sites where my session state gets lost prematurely.

I use the Inproc session provider and 2.0. Which of these are true:

The antivirus software disturbs the session. IIS recycles the app pool every 2 hours and it does not retain the sessions during a recycle. Index server disturbs the session. Anything else that can have disturbed the session?

State Management :: Session Variable Persisting Even After Abandoning A Session - Closing Browser Windows

Aug 5, 2010

I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.

I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.

State Management :: Session Does Not Persist After Postback On Deployment

Nov 22, 2010

I ve been searching for this on various forums and came through a number of supposed solutions which didnt work for me.

My web form works perfectly for me when on development and after publishing on IIS but when I try to access remotely the session value is always null.

I do these things in the following order and when accessing remotely I always get the exception i throw when session is null.

I debugged it and my list is never null when reaching the assignment point.


in webconfig I have the following tag which I saw as an answer in many forums

<sessionState mode="InProc" cookieless="true" timeout="200" />

State Management :: Viewstate And Dropdownlist / Initial Selection Is Lost Each Time The Page Refreshes

Jan 13, 2011

I have a simple search page with a drop down list that I would like the value to persist on refresh..basically the user will select their location from the dropdownlist and this will be used to populate a gridview. After this the page is set to refresh at a set interval and use the same location data initially selected by the user. However the initial selection is lost each time the page refreshes.

p.s system is to old for ajax!

<meta http-equiv="Refresh" content="300" />
<script runat="server">
Dim connectionString As String = ConfigurationManager.ConnectionStrings("****").ConnectionString
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Not IsPostBack Then
Dim conn As SqlConnection
conn = New SqlConnection(connectionString)
Dim Locationcommandtext As String
Locationcommandtext = "SELECT * FROM [Location] ORDER BY [Location]"
Dim loccomm As SqlCommand
loccomm = New SqlCommand(Locationcommandtext, conn)
Dim reader As SqlDataReader
reader = loccomm.ExecuteReader()
Locations.DataSource = reader
Locations.DataValueField = "LocationID"
Locations.DataTextField = "Location"
Catch ex As SqlException
Response.Write("SQL Error:
" & ex.ToString())

State Management :: Multiple Servers - Data Lost

Apr 16, 2010

I have 2 front end servers and 2 back end servers. There is a registration form in my web application. The registration form uses a Microsoft Wizard control. Lets say the Wizard control has 4 steps. After the fourth step, users click "Finish" and I display the "Thank you Message". The way the request is routed between the 2 servers is round robin. So lets say till the fourth step, the response comes from server A. After the user clicks "Finish", lets say the response now comes from server B. After they click "Finish", I am trying to access some information in the Wizard control (like Name, address and so on). Because the servers are now switched, the data is lost (at least thats what I think is happening). So all entries in the wizard control are now blank and when I try to read those values, they are null.

State Management :: Storing Large Data In Session State?

Sep 18, 2010

We have a scenario where we need to store large tables of data on Session in page. on a highlevel we have to store following data

1> A table (table 1) with 1000 rows and 8 to 10 columns.

2> A table(table 2) with 500 rows and 8 to 10 columns (actually user can add the data from table 1 to table 2, so as user keeps on adding from table 1 we remove the data and put it in table 2)

3> Another table(table 3) with 1000-1200 rows each having 3 columns.

We are having a webfarm, so we need to store it in either SateServer of Oracle DB,What would be the performance implications of storing such huge data on the server.

One more thing is at any point of time max of 70 -80 people will be accessing our website, so will this cause any performance degradation?
