Session State Lost Between Ajax Posts?
Jul 16, 2010
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?

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.

I am creating a presentation on basis of some selected values and maitaning the selected values in a session variable named Session("userPref") in collection form.
Now I am opening a TablePreview.aspx page by javascript window.open() function.
On Page_Load of TablePreview.aspx I am reading some values of Session("userPref") and doing some operatons.
For saving the presentation I have created a page wizardsave.aspx.
Now I am opening the wizardsave.aspx from TablePreview.aspx by window.open() function for saving presentation, but on Page_Load of wizardsave.aspx. I found that some value from collection stored in Session("userPref") have lost.

1. I have couple of checkboxes and some text fields outside the updatepanel.
2. Based on the checkbox selection, I will be hiding/showing the fields to user using javscript.
3. I have a upload control in the same page which is placed under the updatepanel. When I upload the file, I will be reading the content of the file and I'm trying to load it into the controls which are outside the updatepanel. As I know the controls won't updated until unless it has been added under the updatepanel.
4. I moved all the controls outside the udpatepanel (checkboxes and textboxes) and placed it inside the updatepanel so that when the file is uploaded I can read the file and assign to the controls.
After this, I was able to assign the values to the control. However, the problem is, the state of the page (javascript hide and show) has not been retained during the postback. For example, if i have 2 checkboxes and 2 textboxes, if i click firstone, it should show the first checkbox. If I click the second checkbox, it will show the second textbox. By default, when the fresh load happens, first textbox will be shown. When I click the second checkbox (its showing the second textbox) and do the postback by uploading the file, the state gets lost and when the page load completes, it's showing the first textbox instead of showing the second textbox.

I'm evaluating using Ajax in a new project and so I've developed a simple web page to test a few things, however even the simplest task seems to cause my session to be cleared. I am using VS2008 with .Net 3.5 SP1 and the page is in my existing solution which has several custom handlers and modules in the web.config. Below is the code I'm using, it's a simple test which puts a variable into the session then on the buttons postback tries to get the same variable, however it always fails as the session is blank.
The Default.aspx code snippet
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" /> [code]....

Here is what I want to do: I have a local site in which I want to display data from a remote site
Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost
Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.
The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself

Have not run the ASP.NET Development Server for a while. Today I copied a production website to my workstation and ran it with VS 2008. The following error message popped up. What is the problem with the ASP.NET development Server on my workstation? The website on the Production server still ran okay.Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection.
If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name.

I have a webpage which includes a telerik grid in ajax mode. The data for the grid is constructed in the controller action used to serve the view, and then stored in the session. 90% of the time its available to the ajax method used to populate the grid. And sometimes its not, which is odd. Some sort of race condition ?

So if my session object is null, how can I recover - I guess I need the productModelId and Revision parameters from the original EditImage call. Are they available in the _EISelect in any way - its posted to, and the post contains nothing useful.
Oh to make this possibly harder, this page will be displayed via an inline frame.

just been trying to recieve the session value from multiple jquery ajax requests on the same domain name. i think i understand that each request is kind of a virtual browser request so the session is mutally exclusive to each request, but there must be a way some how, has anyone solved this. Basically this is what im trying to do:
I have tries using type: GET and POST but still no luck.
First request - Stores the product id in a session

If a normal session timeout occurs we could handle the session timeout.
But say we are using a lot of ajax calls, webhandlers etc. How would we catch session timeout here and redirect to error/login page.

Given this Global.asax.cs:
using System;
using System.Web;
namespace Foo.Web {
[code]....
User hits webapp and is shown Introduction.aspx
User continues using webapp for a few minutes (ASP.NET_SessionId: ublbhu45ji31e055ywqu0555)
User falls idle (doesn't perform any postbacks) for a few minutes
User performs postback
User is shown Introduction.aspx
Second inspection of user's ASP.NET_SessionId cookie still shows ublbhu45ji31e055ywqu0555
Why is the user shown Introduction.apsx the second time inside the same ASP.NET Session? I'm familiar w/ the risk in setting session variables just before a redirect in the same postback, but that doesn't apply here, right?
