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.

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>

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.......................

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?!

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.

Let me explain my Previous look of a Viewer before i used Telerik. this is a Custom built interface , built with normal asp.net and a lot of css at runtime. I am changing to Telerik Scheduler and its doing nice things for me.
I am trying to customize the Viewer. My Previous Viewer was like this
as you can see the above viewer it has 2 Slots that i defined like this in the Database
By the Look at the Old Viewer it combined the DayView and the Month View. Now i am using Telerik Schedular that looks like this when all appointments are binded
Now as you can see this one too, it different views, but the Currently displayed is a Month-view. When a user Clicks on the more it brings it in a Day View. Now i want to implement the Slot style as depicted in the Oldviewer Screenshot. I want to have Sessions and Days at the Top as depicted in the following Screenshot
As you can see the 2nd Period. if an activity of subject takes double period it should be displayed as that and the time should be removed there, there should be Sessions. if i put it in simple english. On sunday 7 i have Seminar as period 1 and Labour Law as period 2 and Period 3 because it is a double period and on the 4th Period i have Advanced Constitutional Law.

I want to redirect the user after 2 mins if there is inactivity for 2 mins. I am not using ASP.NEt membership. And I dont want to use Sessiontimeout for this. Session timeout will logout the user even if he is working on the system. My objective is like screensaver process.
If there is no action for the specified time, the screensaver runs. Similarly, I want to redirect the user to login page.
note that i have already handled it with the following javascript:
[Code]....
Here what my problem is,
the user is working on the site...ok.. he want to see someother site.he browse someother site and works on....or even he can do some other work in his system...but he is active in his system... What this script does is, it automatically logout the user and redirect him to login page. But it should not do while he is active...IT SHOULD REDIRECT IF HE IS NOT ACTIVE REALLY (Similar to Screensaver process)
Is it possible ?

have code that's using session variables; it's both in the master page code behind and in the code behind of some aspx files. I wanted to put this code in a function that's in a different file but when I did that, the statement Session["VariableName"] became underlined in red on the word session. What am I missing?

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

I'm having a problem with a web app I'm managing. Users starting receiving the following error occasionally:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
The problem is that it's not a cluster - it's a single Windows 2003 server. After digging around, it appears that adding a machineKey section and some extra attributes to the Pages directive in my web.config resolves this error:
<machineKey validationKey='MACHINE KEY SNIPPED'
decryptionKey='DECRYPTION KEY SNIPPED'
validation='SHA1'/>
<pages validateRequest="true" enableEventValidation="false">
After changing these two things in my web.config, the error goes away, but now I have a new problem - Instead of an error that my viewstate is invalid, the app just "Forgets" who my user is, and sends them back to the login page. Now, the users are browsing through the application, and then they're unexpectedly sent to the login page, even after they've already been logged in for a few minutes. While I can't force this to happen, it usually happens within visiting 10-12 different pages, so pretty frequently.
I'd love a resolution to this - does anybody know what else might be causing the viewstate error on a single server, or what I can do to ensure that it's validated properly?

I have implemented the basic forms authentication.In web.config I have set the following, in the authentication tagtimeout = "50000000000" Other than that, I have an out-of the box implementation.I have no custom provider.My clients want to pretty much enter the username once a day.The timeout is in minutes, so I am sure that they are not waiting over 5 million minutes,so something else has to be booting them.

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?

I am developing an application for Online Examination. Once a user logs into the system, he is allowed to start a Test; on clicking start test button the user is redirected to the questions page. Now when the user clicks and confirms ending of the test by a button click then he is redirected to the results page.Now what I want here is that when the results page is being displayed the user should automatically be logged out of the system and should not be able to go back to the previous pages by pressing the browser's back button.
The problem which I am facing right now is that when the results page is displayed anyone can press the back button and continue the test and manipulate the result. How can I stop this.

I'm building a website in ASP.NET with C# code behind files, I'll be using the site on shared hosting due to price, and one of my aims was to have a stored procedure scheduled to run every 1 hour in MySQL and update my database.
Unforunately security arrangements on shared hosting means that users cannot schedule stored procedures, so I decided to tackle the problem another way.
I created a timer in my website inside its own class file in the App_Code folder, it basically starts a timer and then the time elapsed event connects to my database and calls the stored procedure. I then built an admin page that allows me to see the status of this thread (started/stopped) and allows me to start/stop and restart it.
It's installed on my test site that I run from my home PC using Win7 and IIS, and it works beautifully, I can stop start the service and watch the database tick up when it's running...
HOWEVER...it only seems to run for 20 minutes before it stops, I thought maybe it was the garbage collection killing it since that's mentioned in some timer examples but I've added a GC.KeepAlive(Timer) and that's not . I'm really stumped as to what is stopping the timer, it's functionality is dead on the money and how I want it, but it just stops, always after almost exactly 20 minutes.

I need to fetch CSV file from a webserver every few minutes.
Here's what I am planning to do:
I will create a webservice "GetCSV.asmx" which will get CSV file from that webserver.
I will create another webservice "RegularCall.asmx" which will call "GetCSV.asmx" every few minutes.
Is my approach correct? Is there a better way of doing this?
I am using ASP.NET web application and JSON webservice for this.
NOTE: There will be NO user intervention and the solution I am looking for is similar to scheduling a task on the server.
