View 1 RepliesIf i stored document id in session variable of one of the page , if i opened new tab of the same browser the session will be exist
How can i create new session when i open new tab
Can I still use Session_OnEnd to trap a session timeout? Is there a better way to trap a session timeout? I want to take the user to a page that tells them the session timed out, and give them an opportunity to re-enter the application in a new session if they wish. How can I accomplish this? Is there still a global.asax file in the .NET 4.0 world?

View 6 RepliesMy ASP.NET 1.1 application is using load balancing servers. Before load balancing servers, there is no problem related to session management. After googling, I found the following two points:
1) Website instance ID must be same on both the servers. When I ran Microsoft provided VB Script to check instance ID. On both the servers, they are same.
2) I have also generated a unique machine key and pasted it in the machine.config on both the servers.
I want to know how can I write custom session management mechanism in ASP.NET. I do not want to use cookies or URL to have my session ID thus I think I can not use SessionIDManager. I will like to save the sessionID in a post variable and at server I will like to extract this ID to map with session.
View 3 RepliesI 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 a problem by getting session which created for new site visit or session expired.
View 3 RepliesI 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 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:

which place(exact folder) the session & session id will be stored?

now if user closes browser. the session does not get killed.
I spoke with friend and he said that cannot be done as sessions are on server.
but i see banking website who kills session when browser is closed.
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 need to make my asp.net session cookie as secure but whenever i check user authentication and after that i am trying to set cookie to true then my session lost my user information and so it always redirect login page. I am settings user to HttpContext.Current.Session["user"] and check every time, is user is valid and if valid then move ahead. but before that i make my asp.net session cookie as true.
[Code]....
but after that i observe that somehow "Session_Start" event gets called.
I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.
View 3 Repliesi want to know if i want to use multiple server for my application. what should i do.e.g. if i used session to store some important data so as session get stored on server if my application use one server and server get crashed then my application also get crashed. So to avoid this problem what should i do (if solution is use multiple servers then how can i do that)

View 11 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)
In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List);
In the Controller I build a viewModel with the data from this session
[Code]....
and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item.
[Code]....
When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList).
return View("view.ascx", viewModel);
When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.
I am using Session variable throughout in my application and my timeout is 1 hour. Here I need to catch the exception for session expires in any global way across my application.
View 3 RepliesThere are various ways to handle session timeouts, like "meta refreshes" javascript on load functions etc.
I would like something neat like: 5 minutes before timeout, warn the user...
I am also contemplating keeping the session open for as long as the browser is open(still need to figure out how to do it though... probably some iframe with refreshing).
How do you handle session timeouts, and what direction do you think i should go in?
am a ASP.NET developer using Facebook Developer Toolkit to develop a facebook flash application with flash developer.When the user plays the game for a certain period of time, there are chances that the facebook session expires and I can't call any Facebook API for processing as a result.

View 3 RepliesI'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.
