State Management :: Session Variable Worked On One Prod Server But Not On Another Server?
Nov 3, 2010
We recently migrated a web app from one Prod server (Prod 1) to another server (Prod 2). There is a session varialbe checked inside the page load event of the default master page. I have enabled session state both in web.config as well inside the pagedirective. The compilation went through without any issue. The web app is also running just fine on the server but the log file keeps logging a warning message. There is no run time error.
"System.Web.HttpException: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration."Any idea why this is happening on one server vs other?

Kindly let me know why my appln redirects me to Session TimeOut page on a simple postback. This doesnot happen on my local pc but happens only on prod. Here is the code I m using on my PageBase.cs 's Init method
[Code]....
And in my web.config:
<authentication mode="Forms">
<forms name=".MY-AUTHPORTALNAME"
slidingExpiration="true"
defaultUrl="Default.aspx"
loginUrl="Login.aspx"
protection="All"
timeout="9999"
path="/"/>
</authentication>
<sessionState mode="InProc" cookieless="false" timeout="9999" />

In my web application, I set the mode of session state as State Server and point to another server. After run some days, I always meet following exception:
The state server has closed an expired TCP/IP connection. The IP address of the client is 192.168.80.157. The expired Read operation began at 08/25/2010 14:18:03.

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

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);
}
}

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 use some session variables to get the job done(shopping cart, etc) but it is not stable..manytimes I get no items in session object and other times(refreshing the page) I get missing data...I downloaded the entire site code to my local pc and debugged it and run it succesfully without any session data missing...When I run it in the server, I get bad session again: no products in shopping cart or products with missing quantities...
The same website runs smoothly in our production server too....The problem is with our development server...

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?

I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page

I have some code in my page load event where I just want to fire once when the user opens the Browser. The only issue is if you open a new tab with the same website the session variable does not reset. Is there a way to reset the session variable when you open a new tab or do you have to take the whole web browser down for it to clear the session variable.
In Global Page:

I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.

I have two projects ,one is webforms and other is Business logic, i am storing username in Session Variable, i have audit module in businss logic which has event handlers to do auditing on object create / remove. i want to store username in audit trail, i want to save username in some global place which is session bounded so that i can get the username in my audit module.i dont want to refer System.web, or httpcontext in my businesslogic project.pls help how i can acheive this. i found this article but cudnt understand much.
"Now one option if you want to have your DLL pull the stuff from Session is to abstract out session. So you could define an interface like IStorage, that your library will know how to use. Then you can have a SessionStorage or MemoryStorage class and use IoC to inject the appropiate class into your library classes. This gives you the freedom to code it how you wanted it to be coded without tying your code to Session. Oh and one other benefit if done properly can be used to not tie your code to session in the web either.

I am using ASP.NET 2.0I am little bit confuse about using of Session Variable. I have a three page web application. When a user login, after verification of user credentials I get user ID from DB and store this ID in a session variable.Session("USERID") = 56by using this ID I can get 20 different values from database as User Full name, user date of birth, user location, user date of joining, User Commission rate etc. I need some of these values in Page 1, some in page 2 and some values needed in Page 301. After successfully login and getting the User ID, I take all these 20 values from Data Base and store these values in an ArrayList and store this ArrayList in a seesion and whenever I need to use any value I take these values from ArrayList which is save in Session variable.

I have this setting in web config for session.
[Code]....
On localhost works well. On the hosting server expires very quickly. Sometimes after a minute, and sometimes after a few minutes.
I tried mode="StateServer" and mode="SQLServer", but first works the same, other doesn't work. The next problem is that End_Session in global.asax doesn't executes if mode is not InProc. And I need this.
How could I achive that session expires only when browser is closed or other url is typed. Just setting timeout doesn't work.

I have an scenario where, in the test server the timeout works fine, as defined in the web.config (60 minutes) but it ends prematurely (3 minutes or so) in the MSSQL server. Both are using tables from the MSSQL, the only difference resides in the App_Data folder, which is not in the MSSQL server, as the roles and membership are managed by the LocalSqlServer.

This is the strangest problem im facing(may be i missed something). The application works fine locally, but when uploaded on the live server. the session values are not retrieved properly.
i have stored a value in a session in master page's code behind. and afte the page is redirected is to another page, there im not able to retrieve the session value.
why this is hapening.. i remind you this is working perfectly on local server. problem is only when published on live server.

I'm looking store an ArrayList into a session variable, but am having a few problems. Can you spot anything wrong?
public partial class _Default : System.Web.UI.Page { ArrayList score = new ArrayList(); protected void twist2(object sender, EventArgs e) { int a = 11; int c = RandomNumber(a); score.Add(c); score = (ArrayList)Session["scoreData"]; Result.Text = (c).ToString(); String Result_id = Result.Text; int total = 0; //Session["scoreData"] = score; for (int i = 0; i < score.Count; ++i) { total += (int)score[i]; } Sum.Text = (total).ToString(); String Sum_id = Sum.Text; }
