State Management :: How To Abandon A User's Previous Session
Jun 11, 2010
In my ASP.NET application I need to allow only one session for a user ? When a user does login more than once, I want to get to user's previous session and abandon it. I'm keeping track of all user sessions by means of session id. But Session.Abandon is available only for the current session associated with a request and not previous sessions. I have the session id of the user's previous session but how can I end it ?

Session.Abandon() in not working ASP.NET 2.0 (C#) in a few cases. In the same application its working fine in other places.
< sessionState
mode="StateServer"
cookieless="false"
timeout="20" />
The session mode is "SateServer".

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?

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:

I am a little bit new at handling multiple sessions congruently.
Basically i have created a chat application. In which i have a moderator page.
Now the moderator has the privilege to block particular users from the chat. Every user including the moderator has a session variable defined as Session["UserID"].
e.g for the username "moderator" the Session["UserID"]=moderator.
Now as i am logged in as the moderator how do i delete the session of a particular user whom i want to block the chat from commencing.

I need to store a large amount of data in user's session but I guess using Session Object is not the best way of doing that. Is there any other way around??? Remember I don't have small variables to store, I have large collections.

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.

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);
}
}

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.

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?

I'm using the following line of code to display the number of users currently logged on:
lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()
I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?
