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 asp.net 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.

I need to make my asp.net session cookie as secure but whenever i check user authentication and after that i am trying to set cookie to true then my session lost my user information and so it always redirect login page. I am settings user to HttpContext.Current.Session["user"] and check every time, is user is valid and if valid then move ahead. but before that i make my asp.net session cookie as true.
[Code]....
but after that i observe that somehow "Session_Start" event gets called.

I am working on an asp.net 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 (asp.net 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?

I have a problem with a couple of web sites where my session state gets lost prematurely.
I use the Inproc session provider and Asp.net 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?

Existing applications works fine with IE 6 and 7, the problem occurs only with IE 8. A new session is created everytime a window.open is used to open a new asp page. This does not happen in IE 6 or 7.

SessionStateModule raises a Start event with a new seesion. Is there a pointer to "deep dive" information?
In particular,
(1) I want to preserve Session state information across a postback to external (web-based) services in my VS 2008 development environment, but am finding that my code is triggering the creation of a new session.
(2) I am using IIS to host WCF Service calls, and it appears that many of those calls trigger the creation of a session. I would like to dive deeper into this, and try to manage (reduce) the number of sessions that are created and their behavior.

In my webapp page i load a custom user control, this uc loads data from an xml file in a JSGrid. All this works fine and uses callbacks. The uc is the callbackhandler and thus implements the icallbackhandler interface. Now, i gave this uc some properties, like the path to the xml file. After each callback the uc loses the values of its properties. Currently i'm including the path in each callback itself so i can load the file each time i need it, but this isn't the good way i think.
I tried solving this with viewstate but it doesn't work, a callback also seems to erase the values of the viewstate.
Is there a way to keep these values stored in the uc instance? Maybe a way to disable the erasing for each callback?
Also each callback contains "Changes", this has al the changes that were made to the grid. So when all the changes were made in the grid, i want to get these changes in my page that contains the uc in order to decide ther what to do with this data.

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.

I have an asp.net login page, which when initialized sets some session variables. When the user clicks login, an AJAX request is made which validates the user and sets additional session variables and returns a result to the client. The client is then redirected based on the login result. In the redirected page, I can access the session variables set when the login page was initialized (i.e. before the login) but none are present for those set during the login validation (part of an ajax call).
is this expected behaviour? Why would an ajax call generate a new session and thus cause the data to be lost?
