State Management :: Session Suddenly Times Out On One Application?

Aug 10, 2010

I have a web application that was working fine. I had to make minor changes that had nothing to do with the Session object in any way. When I run local everything works fine. When I publish to our testing box it all runs fine. When I publish to production it times out on the Session object. Dozens of other applications on the production server run fine and have no trouble with Session.

It does not matter if the line is:

Session("PreferredName") = sPreferredName
or:
sPreferredName = Session("PreferredName")

I had the server admin remove the application pool and directory and recreate them and then I republished and it still happens.

State Management :: Session Suddenly Become Null - Need To Rebuild

Jul 28, 2010

I have a strange problem with the session. I have global.asax with code in the session_start event. This code calls some code that I have in a helper class. When I first run the project in debug everything is fine. However when I stop debugging and then re-run the project it fails and I have discovered that once the code in the helper class is hit the session is null. If I look in the global.asax session_start code the session is instantiated before it enters the helper class. If I then re-build the project and the re-run it everything works fine again! Why does the session suddenly become null and why does a re-build fix the problem?

State Management :: Session State Expiration After Application Pool Recycle?

Nov 1, 2010

All we have a global ships position tracking website which runs smoothly until IIS application pool recycles.When there is workerprocess recycling looks like session state expires as a result i loose all session data and when customer clicks refresh button he is redirected to login page.

In web.config Session state mode is set to InProc so i changed it to State Server but to my luck i have MAP object which is not serialiazable which is causing the maps from not appearing on the website.I tried adding serializable attribute to the object class but still not succesfull.Our website is accessed by our customers whose count is more than 1000.

Changing the session state mode from InProc to StateServer can really slow down the response time so
Is it good to go further fix the serailizable issues and move to state server?.

Is there any way I can retain my session data when application pool recyles?..

Stopping Application pool from recycling may not be a good idea considering health factor of web server.

State Management :: Application State And Session State?

Oct 2, 2010

User Interface: 2 Labels; 1 Buttons

Requirements: Create a Web Page in ASPx that will do the following:

1)One label will provide a count of how many times Button 1 has been clicked in the current session.

2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

aspx.vb

Partial Class _Default
Inherits System.Web.UI.Page
Dim clickcount As Integer

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Session("ClickCount") Is Nothing Then
clickcount = 0
Else
clickcount = CInt(Session("ClickCount"))
End If
If Not IsPostBack Then
If Request.Cookies("UserName") IsNot Nothing Then
Label1.Text = "Welcome Back " & Request.Cookies("UserName").Value & "."
End If
End If
Dim clickCounta As Integer = CInt(Application("ClickCount"))
End Sub
Protected Sub PostBackSession_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles PostBackSession.Click
clickcount += 1
lblClkCnt.Text = "Current Click Count is " & clickcount
Application.Lock()
Dim clickCounta As Integer = CInt(Application("ClickCount"))
clickCounta += 1
Application("ClickCount") = clickCounta
Application.UnLock()
AppClick.Text = clickCounta
Dim nameCookie As New HttpCookie("UserName", _
TextBox1.Text)
nameCookie.Expires = Now.AddYears(1)
Response.Cookies.Add(nameCookie)
End Sub
Protected Sub PostBackSession_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles PostBackSession.PreRender
Session("ClickCount") = clickcount
Application("ClickCount") = clickcount
End Sub
End Class
global.asax
<script runat="server">
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Dim clickCounta As Integer = CInt(Application("ClickCount"))
Application.Add("ClickCount", 0)
End Sub
Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
Dim clickCounta As Integer = CInt(HttpContext.Current.Application("ClickCount"))
End Sub
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when an unhandled error occurs

State Management :: Session And Application Cache Items Disappear?

Mar 31, 2010

i've been coding an asp.net site using VS2005 for about one month.

my site uses both application cache and session cache to save data.

the syntax i use for application cache is :

HttpApplicationState appState = Application;
appState["someKey"] = "somevalue";

and for session cache i use :

HttpContext.Current.Session["someKey"] = "Somevalue";

my site is deployed on three standalone servers - each server runs a diffrent instance of the site.

two of the servers work just fine, the third has a stange problem - and also has the least free memory space.

in this server items start dissapearing from both the session and application cache - note that i set no expiration date to the cache items.

does anyone know why this could happen?

seems to me there is perhaps some memory limit for cached items setting that i am missing.

State Management :: Session Variable And Multiple Web Application Instance

Oct 13, 2010

I have a web application using window authentication. There are a search page and a edit page in the application. In search page, user can enter some search criterias in the textboxes and the search result will be displayed in the gridview by clicking the "Search" button. User can select any row from the gridview and it will take him to the edit page. In the edit page, there is a "Back" button to take the user back to the search page. I use session variables to remember what the search criterias the user entered in the textboxes and what page number the user was in the gridview. So when the user goes back to the search page, the textboxes are pre-populated with the search criterias and the gridview is displayed in the correct page number.

The problem is: If user1 opened one browser window and did a search using search criterias1, then user1 opened a 2nd browser window and did a search using search criterias2. When the user1 went back to the search page from the edit page using the first browser window, all the textboxes and page numbers are from the 2nd browser window, instead of the 1st one. Can anyone explain this problem to me and how to prevent it? It will be helpful too if you can give me some links about the similar problem. I am thinking if the same user logged on two different machines and did the search on each machine, what is the result?

State Management :: Save Session Data To Oracle 10g R 2 In Application?

Feb 26, 2011

I am creating a web application that will be running on an infrastructure which will utilise a number of web servers, web gardens and a load balancer.

As the application is using Sessions, and that our application is using Oracle as the database, we would like to use the database to save the Session data. However, I am struggling to find any good examples on how to do this with Oracle.

I note that Oracle provides the following class: Oracle.Web.SessionState.OracleSessionStateStore, but I am unsure what I need to do in the Code Behind and what if any tables do I need to create in the database.

State Management :: IPartitionResolver.ResolvePartition Called Many Times Per Request?

Jan 6, 2011

I have a .NET 3.5 web application that uses SQL Server for its session state store. To improve scalability I wrote a class that implements IPartitionResolver that figures out which instance of SQL Server to use for a users session. All of this works great
and just as expected.

However, when I was debugging one day I set a breakpoint at the bottom of the ResolvePartition method to make sure the correct connection string was being returned. To my surprise this breakpoint was hit many (~5-10) times per request! The same is true about breakpoints in the IPartitionResolver.Initialize method.

Does anyone know why this is? It seems to me that you would only need to call these methods once per request. It's not like the users session is going to move to a different instance of SQL Server mid request.

State Management :: Using A Cms Product To cache Every Page - Get Quick Response Times?

Jun 4, 2010

I am using a cms product that likes to cache every page so that you get quick response times. The downside of that is that pages can get stale. My question is: are there different caches per user? Does asp.net keep track of caches on a per user per site basis? That's what is seems like to me, but I can't seem to find it documented anywhere. With this cms, they have a load of hashtables keeping tabs on the modified pages. If you clear out the cache, log out, and log back in again as another user, you still have stale information. The only way to get the information to be current for all users is to recycle the app pool, which is something you don't want to do too often ( kinda like pulling the emergency brake on the train ).

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?

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?

State Management :: Asp Create New Session State Cookie Each Time On Debugging?

Jan 21, 2011

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?

State Management :: Losing Session State In Global.asax File?

Feb 2, 2011

I am trying to set a session variable in the global.asax file and keep running into the problem that the Session is null.

I am running my application in VS2008 and using asp.net 3.51.

Here is my code:

1. In my web.config file I have enabled the session state and added the following line;

<sessionState
cookieless="false"
mode="InProc"
timeout="60"
></sessionState>

2. In the Session_Start procedure in the Global.asax file I set the session variable to a default value.

[Code]....

My problem seems to be that when the Application_Error procedure is executed the session state is lost.

Does anyone know why the session state isn't available in the Global.asax file.

State Management :: Session State Returning Null Values?

Apr 29, 2010

I have a clear button and a textbox in an aspx page. I set the session variable in this page as

String str = Textbox1.Text;

Session["TypeIds"] = str;

and I clear the sessions in a clear button event as

Session["TypeIds"]=null;.

Then when the user types some value in the textbox ,on Response.Redirect on another aspx page, the session variable returns null values.It does not retain its session state. The session state has to be maintained in the next page. Is it because this clear button event and setting explicitly to null creates this problem?

State Management :: Session Variable Authentication State Timeout?

Dec 3, 2010

I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:

[code]....

Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?
