View 18 RepliesI 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 asp.net 3.51.
Here is my code:
1. In my web.config file I have enabled the session state and added the following line;
<sessionState
cookieless="false"
mode="InProc"
timeout="60"
></sessionState>
2. In the Session_Start procedure in the Global.asax file I set the session variable to a default value.
[Code]....
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.
how to get sessions in the global.asax, but I still cant get it to work...for some reason my session throws NullExceptions..the sessions are set from another page add looks something like:
[Code]....
And once I try to get those session values I do the following in the Global.asax:
[Code]....
But as I said, for some reason I get a NullException once I try to get the values...and they do have the same session-name,so they shouldn't be null..
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

View 1 Repliesi'm using asp.net 2.0.
there's a way to add an handler to manage the session_end event without using the global.asax?
(i can't modify my httpapplication code so i need to add the handler externally to it)
I have a simple aspx Page, which html contains:
[Code]....
and code behind:
[Code]....
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:
[Code]....
This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.
Suppose my website address is like http://localhost/MyWebsite
I wanted to access this url in Application_start event in global.asax, Can i some how get it?
[I know i can get it via application_beginrequest or other event]
What is the difference between the 2? Ex:
Private Sub Globals_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.BeginRequest
vs
Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
I am have declared a session variable in login page of my application. I want to access that session variable in Application_BeginRequest of global.asax file. But I am not able to do it. Could you please suggest how to access the session variable in my global.asax file
void Application_BeginRequest(Object sender, EventArgs args)
{
string language = HttpContext.Current.Application["language"].ToString();
}
I'm trying to use SESSION in my MVC application.I wrote following line in Global.asax in Application_Start() method file:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
//uzupełnij zmienne sesyjne
HttpContext.Current.Session["LOCATION_ID"] = 15;
RegisterRoutes(RouteTable.Routes);
}
I also enabled SessionState in Web.config by addind following line:
<sessionState mode="InProc" cookieless="false" timeout="120" />
And when I run the application I'm getting this exception:
Szczegły wyjątku: System.NullReferenceException: Odwołanie do obiektu nie zostało ustawione na wystąpienie obiektu.
Błąd źrdła:
[Code]....
Wiersz 31: //uzupełnij zmienne sesyjneWiersz 32: Wiersz 33: HttpContext.Current.Session["LOCATION_ID"] = 15;Wiersz 34: Wiersz 35: RegisterRoutes(RouteTable.Routes);
How to page redirect in  Global.asax Session_End ?
View 1 RepliesI want to be able to log when a user ends their session on our application and record whether it was a sign out or a the session expired. I am using
cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));
to set a new sessionId on sign out, but when the session expires, the sessionId is reused if the browser instance is not closed. In my web.config I have used
<sessionState mode="InProc" timeout="1" cookieName="session" regenerateExpiredSessionId="true" />
but still get sessions reused. I can't kill the cookie in Session_end() because I don't have access because there is no HttpContext or request, so I can't reset it that way. how I can force a new sessionId from the Global.asax.cs file?
I want to use something better thatn using the session to store global values, because it has somw problems

View 3 Repliesi have 2 web application that resides in 1 IIS7 application via Virtual Directory, i hope to connect the 2 website via Session, my question is can i pass a session value from website 1 to website 2?
View 3 RepliesI have been trying unsuccessfully to retrieve a Session varaible from within an ASHX file that i'm using to build an XML file.
What I am trying to achieve is quite simple really.My ASHX file is used to dynamically build an XML file so that I can then bind it to a TreeView control later on. However the dynamic part isn't quite working because the ID that I need from the session seems to not be passed into the ASHX file.
I have tried using the following methods to do this:
1) Include interfaces IRequiresSessionState and IReadOnlySessionState
2) Tried accessing the value like this: Session["ID"] or context.Session["ID"] or HttpContext.Current.Session["ID"]
I am setting the Session variable in the MasterPage's code behind.
I tried to set the session state in my webconfig file and got this error.. <sessionState timeout = "60"/>
Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
However if I tried to set it in anther aspx page it seems fine...is there a reason for setting up the virtual directory as an app in IIS ..what are the benefits of doing this, and is it always necessary?
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:
[Code]....
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.
i am new in asp.net form authentication and sessions
i would like to know how to save session in masterpage or in global.asax and how to clear session.
how to better handle session timeout by redirecting to a page.
