VS 2010 Sessions Variables Getting Lost?

Jan 28, 2012

This is my page code

Code:
Protected Sub btnLogin_Click(sender As Object, e As EventArgs) Handles btnLogin.Click
Dim blnLogin As Boolean
blnLogin = Login(txtUserLogin.Text, txtPassword.Text)
If blnLogin = True Then

[Code] .....

So after the user presses the Login button there should be 3 variables stored in a session, this works (checked using trace='true')

Session State
Session KeyTypeValue
LoggedInSystem.String
LoggedInUserSystem.StringUser
LoggedInIDSystem.Int322

That's fine. Now I click on the AddToWall button to check if I can get the LoggedInID, it shows an empty messagebox.

In the trace there are no Sessions keys left.How can I make it keep the keys after postback/after clicking on buttons?

Note: When calling GetFriends(Session("LoggedInUser")) in the same sub as the Login button the variable does get passed to the class with sub GetFriends()

Here's my web.config

Code:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<sessionState timeout="30" />
</system.web>
</configuration>

Asp - Losing Session Variables - What Exception Might Cause Sessions To Be Lost

Oct 1, 2010

I have health monitoring enabled on a production system (asp.net webforms .net 4) and I see that there's a lot of errors being sent to me indicating that a session variable has been lost.(I am trying to attach something out of session state to a entity framework data context and get a "Value cannot be null, parameter n ame entity" error). So somehow the session variable now contains null and not an object. Interestingly we have the same application deployed on two separate servers - one DMZ server for external users and one internal server for internal users. Both of these applications on two different servers seem to have the same problem.

Health Monitoring is also monitoring lifetime events and I can see from this that we do not have something like IIS recycling, config changes, changes to bin folder, recompilations etc, occuring. I've read this page: [URL] I can confirm that it's not a Response.Redirect problem because that's not happening - this is an online application form - it puts an object in session state on page_load and there's a multiview - when "next" is pressed, the object comes out of session state, is attached to the data context, changes are made from the web form and the datacontext updated. So there's no response.redirect happening.

I can also confirm the details in "Update 1" and "Update 2" from that link are not relevant to me - there is only 1 worker process running in the application pool and the server name or web address do not contain underscores. I also persued the possibility of session timeouts occuring but they should be handled by other code which is running to detect session timeouts (see: [URL]) which I have tested over and over - Part of the problem is I just cannot reproduce this error myself.......................

VS 2005 Lost Sessions After 30 Minutes?

Mar 24, 2010

I have an application using login-controls.

I have this code in my webconfig:

<authentication mode="Forms" >
<forms loginUrl="default.aspx" protection="All" defaultUrl="index.aspx" timeout="100000"></forms>
</authentication>

My problem is:

If I do not activate my application for 30 minutes (my customers wants to be online all day without logging out) my session for user login is lost. How can I automatically refresh my sessions if there has been no activity for e.g. 10 minutes? It's a sort of keep-alive that I want. I thought the problem was sloved when I set the timeout to 100000 but it doesn't help

Note. My application works with the remember me function but it losses its sessions after 30 minutes.

Sessions Lost When The Page Is Reloaded (ispostback = False)?

Feb 27, 2010

I have an asp.net page that sets a few session variables. On my development machine (localhost), I do a postback and the session values are still populated.

When I Reload the page by clicking on the url bar and pressing enter the session variables are still there.

However when i deploy this page to a webserver, the page still retains the session values when doing a postback, but as soon as i click the url and press enter the session values are lost (where the ispostback = false)

But when i press the refresh button the session variables are present (but i do get a popup warning me that the page data needs to be resent!)

i am running IE 7, and the webserver is iis6 what am i doing wrong?!

State Management :: Sessions Consistently Lost- Until Repeat Visits

Apr 23, 2010

I have a session state that myself and others on my team have been bashing our heads against the wall for the past week. We have tracked it down to the following:

1) Frame page containing content pages creates a session

2) Content page creates a session, stores data in the session

3) User changes drop down list with SelectedIndexChanged autopost back and displayed fields are changed using an UpdatePanel. A new session is created, data stored in the prev. session is lost
4) User posts back, no session is created this time, however the post back fails because the session from step 2 is lost.

Now, a user closes the page, comes back, and it actually starts to work:

1) Frame page containing content page opens (no new session)

2) Content page loads data, stores in session (no new session)

3) User changes drop down list with SelectedIndexChanged auto postback and displayed fields are changed using an UpdatePanel. Sesson NOT lost

4) User posts back form, success

ASP.NET on the first visit to the site insists on creating 3 sessions, we log it in Session_Start. I can't think of any reason this should happen. I've been told the frame will always be on a seperate session; thats fine, its only being used to setup scrolling
within a frame in Dynamics CRM. The biggest question is why when we insert data into the session in step #2, it is discarded in step #3.... but only during the first visit to the page!

I've never seen this session behavior before; we don't have any session abandonments in our code, and we never clear session objects, so there shouldn't be any reason for the session to be lost.

Session Variables Get Lost On Browser Close

May 18, 2010

I'm creating a site. Below is my authentication tag and session tag in web.config

<authentication mode="Forms">
<forms protection="All" loginUrl="Pages/Log In/Login.aspx" name=".ASPXFORMSAUTH" cookieless="UseCookies" requireSSL="false"
defaultUrl="Pages/Common/Default.aspx" enableCrossAppRedirects="false" slidingExpiration="true" timeout="30"path="/">
</forms>
</authentication>
<sessionState mode="InProc" timeout="30" cookieless="false" cookieName=".ASPSession"/>
And I have a custom Membership Providor....
<membership defaultProvider="SqlMemberShipProvider" userIsOnlineTimeWindow="15" hashAlgorithmType="">
<providers>
<clear/>
<add
name="SqlMemberShipProvider"
type="RoalManagement.SqlMemberShipProvider"
connectionStringName="SqlServices"
enablePasswordRetrieval="true"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
writeExceptionsToEventLog="true"
applicationName="OnlineOnTheWeb"
minRequiredPasswordLength="6"

maxInvalidPasswordAttempts="3"
requiresUniqueEmail="true"
/>
</providers>
</membership>

Now in login page after firsttime login i set some session data... like
protected void Login_LoggedIn(object sender, EventArgs e)
{
//.....
Session["EMPLOYEELOGGEDIN"] = "Y";
//.....
}

Now say i close the browser... and next time when i open the site it takes me directly to the default page [Login_LoggedIn is not called accordingly]... because i'm already logged in for 30 mins acc. to configuration. but as my session id gets changed i can't access Session["EMPLOYEELOGGEDIN"] from any page in this time. It always returns null. But how do i get back the previous session for that person?

Session Variables Lost On Postback Using AJAX?

Jun 7, 2010

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]....

Web Forms :: Session Variables Value Lost On Page Refresh?

Jul 27, 2010

I am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.

Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");

which takes it to the Data Entry page where user updates the information and save the data.

The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.

VS 2010 - SQLState Server Destroy All Sessions When 1 Browser Is Closed

Oct 31, 2011

I have started using an SQLState server to store my objSessionData object and many more session data.

<sessionState mode="SQLServer" sqlConnectionString="Server=**********;UID=*****; PWD=***" cookieless="false" stateNetworkTimeout="20" timeout="60" />

I open two browser, log into the application, proceed in a few pages to store some information in the objSessionData for both browser (2 differrent session).If I close the first broswer, and now keep on going on the 2nd broswer, everything that was in session is now lost.It looks like Session 1 detroyed session 1 and session 2.I have tried to change the cookieless to TRUE and when it is set to TRUE, I do not get this problem at all.

State Management :: Session State Variables Getting Lost?

Jun 28, 2010

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?

How Does IIS Recognize Different Sessions In .NET

Aug 19, 2010

Suppose I have logged into an application which is running from IIS. Now I haven't logged out, but closed the browser. And when I'm accessing the application again, it defaults to the login page. How does IIS recognize that it is a new request and redirects the user to the login page?

I have another doubt. Suppose if I'm not closing the browser, which I used when I logged in. I'm opening the new browser to request a page from same application. IIS recognizes that it's a new request to the application and redirects the user to login page. Why does it not use the existing session or cookies which the first browser uses?

We say http is a stateless protocol. Once the page is requested i have logged in.And http protocol connection will be terminated between IIS and browser right? Then iam navigating to other pages in that logged in application. Now iis recognises user has logged in this browser. But when i open a new browser and request that application how does iis recognises it is a new request. Since the http protocol is disconnected, how it works in the first case

C# - How To Share Sessions Between PHP And ASP.net Application

Mar 30, 2010

My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database.

(e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application)

How can we share the session between and PHP and an asp.net application?

And does anyone have a hint for this 'coexisting' thing, that might be useful in development?
