State Management :: Setting Session Variable From Formview

Apr 13, 2010

I'm building a site (it's amazing how much you can do and still not know what you're doing).I have my visitor login from a login.aspx page and, when authenticated are redirected to a Portal page. On that Portal page at pageload I set a Session variable "UserName" using the User.Identity.Name like this:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If User.Identity.Name <> "" And User.Identity.IsAuthenticated = True Then
If Page.IsPostBack = False Then
Session("UserName") = User.Identity.Name
End If

State Management :: Accessing Session State In A User Control?

Sep 1, 2010

We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control?

State Management :: Secure Query String Or Session Variable

Aug 30, 2010

Example scenario:
User login has a list of associated 'accounts' it has access to... this list of accounts is stored in a database table, say tblAccountAccessControl, something like:

login, accountID
userA, account123
userA, account456
userA, account798
userB, accountABC
userB, accountDEF
etc..

This info is used throughout the web application and determines the 'domain' of information the particular login has access to. For example there are many other tables that have the 'accountID' field and whenever a page pulls data from the table it only pulls data that the currently logged in user should be allowed to see, based on that tblAccountAccessControl data.

The security question:
Do I need to query the database every time I need to get this list of allowed accountID's? I was about to use a plain old query string to pass a particular accountID to another page but quickly caught myself as I realized that would be a major security flaw (the receiving page was going to use that accountID to grab info from the database, and there would be nothing preventing a user from simply typing in a url manually to get data from an accountID they are not supposed to be allowed to view). So I then thought I'll just store the list of accountID's in a session state variable so they will be carried with the user throughout the session.

But then I remembered there are tools out there that allow you to easily intercept and modify asp.net viewstate information and I'm not sure if that would included session state variables, but I'm guessing they would. Is there a way to create a secure query string? If I used session state would that session state information be exposed and modifyable by utilities out there? Am I just stuck having to query the database every time I need this info to assure security? What about encrypting it and then storing in session state variable (just thought of that one)?

State Management :: How To End User's Session

I have a very basic application with user authentication. I also have a grid in my masterpage that shows all the users logged on. However, after a user logs out, it still shows them to be logged on in the users grid for the duration of the session, which is 20 mins. How do I get the grid to exclude users who've logged out? Here's the code behind for the grid:

State Management :: Passing Session Value / When User Chooses Some Products In His Cart, He Is Prompted To Enter Login Details?

May 27, 2010

I am working on a site in which some pages are to be run on secured server(ie https) & some on non-secured(ie http) eg Login, User Information, etc. will be run under https & View cart, etc. are to be run on http. Now, when user chooses some products in his cart, he is prompted to enter login details. After he fills in his login detail(ie in https), he is redirected to Checkout. But here the Session doesn't picks the value and it shows Session[UserID] value null. So, rather then redirecting to Checkout it shows MyAccount page. Does anyone know how to pass Session Value from https to http.

State Management :: Session Mode State Server - Sending Asynchronous Request

Nov 5, 2010

Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.

But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.

<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.

SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}

State Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode

Dec 12, 2010

I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

I checked the stack trace and its complaining about

[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",

[Code].....

I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.

State Management :: Recreate State Session Database In SQL Server 2008?

Apr 5, 2010

Our ASP.NET App uses ASP State Session Management and has been rebuilt about 2 years ago [With .NET Framework 2.0]. We are currently in .NET framework 3.5 and have moved to SQL Server 2008 - but continue to use the same ASPState database. The State database has been upgraded to SQL Server 2008. Since then we have are seeing timouts/locks on ASPStateTempSessions table. I am wondering if we have to rebuild this database from scratch with some newer scripts?
