Can a user's session and their security ticket expire at different times?


Hi there,

If a user's security ticket and session state are configured to expire after twenty minutes, is it possible that one could go before the other? So for example, a user could have access to a protected web page but their sessions has been lost?

Cheers, WT.

SQL Server Session state problem.


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.

Datatable in session


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.

Session Timeouts


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 requests
3) its not like a connection to the DB where you can conceivable run out

Session with Crystal Reports on IE 8



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
            .ContentType = "application/pdf"
            .AddHeader("Content-Disposition", "inline; filename=Report.pdf")
