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 3.51.

Here is my code:

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


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


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 :: Global.asax To Load Up Several Session Variable When A Session Starts?

Sep 14, 2010

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

State Management :: PostBack Triggers Session_Start On Global.asax

Oct 6, 2010

I have a simple aspx Page, which html contains:


and code behind:


This is quite simple. When I press btn1, it sets correctly the Session Key. And this is then the issue arrives: When I press one of these buttons, this is the sequence of what happens:

Global.asax: Session_Start
MyPage.aspx: Page_Load ╗ btnX_Click

So, everytime there is a PostBack, even before the Page loads, the session starts and generates a new Id. This way, I loose everything during the PostBack. My Session State configuration:


This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.

State Management :: Session Became Null - Maintain Data?

Aug 17, 2010

I have a requirement where i need to download mutiple files as a single zip file.There is linkbutton named HOME as well in the page. when this linkbutton is clicked it should redirect to homepage.aspx. I found a ICSharpCode.SharpZipLib.dll in net and used in my website. Here is the code


With the above code i got the expected result i,e. i can zip the files and save on client system. But the problem is after saving/canceling the zip file if user clicks on linkbutton in the page_load event Session[getdata] became null. there is no data in Session. what might be the problem? Actually it should redirect to homepage.aspx but its going to login.aspx because Session[getdata] is null.

Why HttpContext.Current.Session Is Null In Global.asax

Nov 15, 2010

I'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request. I'm using the 'Application_AuthenticateRequest' and the 'Session_Start' methods.

First round:

AuthenticateRequest called. The following code ran:


The _current variable is a private static field published through a static property. In the first round the Session is null, and I think it's ok because the Session_Start not called yet. The Session_Start looks like this:

protected void Session_Start(object sender, EventArgs e)
Session["EMPLOYEE_DATA"] = EmployeeFactory.Current;

In the next round the Session_Start is not called of course but in the AuthenticateRequest I can't access to the session. The HttpContext.Current.Session is null and the this.Session reference throw a HttpException says the "Session state is not available in this context".

However I can access the Session from any of the page_load events but it's a bad practice I think that I put authentication every page_load.

Setting A Session Variable In Global.asax Causes AJAX Errors

Mar 26, 2010

I'm getting a very peculiar problem with my application, it took me an age to track down but I still don't know what is causing this behaviour.

If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.


I have file called JScript.js containing the code:

function myAlert() {
alert("Hi World");

And in my Default.aspx file I reference the js with the code:

<script src="JScript.js" type="text/javascript"></script>

And in the body onload event I call the myAlert() function:

<body onload="myAlert()">

And finally in the Global.asax file:

Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub

If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.

State Management :: Serializing To File System To Maintain State?

Oct 25, 2010

I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.

These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.

My question is what is the best way to do this, since I have several classes ..
