View 2 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
i'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)
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 2 RepliesWhy Session_OnEnd does not fire in state server & SQL Server modes....... i mean what is the speciality in InProc mode that Session_OnEnd fires in that mode only ????
View 1 RepliesCustomer 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 = '';

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?

#Newbie alert# Only 8 months experience with school education back in 2002.
I'm using VS 2008, C# 3.5 to develop my own login system for our company website.
Originally we have a "simple" design which only had a login and order page.
That order page needs to be opened for 10-12 hours at the time while our stores are opened without having to relog into the system for each query.
We also have a requirement that some users need to access 2 different compagnies (separate inventories) which require 2 different logins.
I solved that "cross over" session problem by moving all the values into viewstate with my own viewstate manager class right after the login.
Now my problem is that we are adding more and more pages and I don't want to be stuck with the problem to resave the viewstate to session and then back on viewstate for every menu items and buttons.
Is there a way to create some sort of items list of all the sessions opened by the user and only transmit that from pages to pages?
I have a application where login details are in 1 database and user details are in another database.Different cities have different database with common login database.As soon as user logs in i save the connection string name of its associated city database in a Session to access through out the application.Was wondering if this is the best possible way to do this? Will this cause a problem in Web Farms? Please let me know what is the best possible way to save a value which can be accessed through out the website and till what time is the value valid or expires?

View 5 RepliesI have 2 front end servers and 2 back end servers. There is a registration form in my web application. The registration form uses a Microsoft Wizard control. Lets say the Wizard control has 4 steps. After the fourth step, users click "Finish" and I display the "Thank you Message". The way the request is routed between the 2 servers is round robin. So lets say till the fourth step, the response comes from server A. After the user clicks "Finish", lets say the response now comes from server B. After they click "Finish", I am trying to access some information in the Wizard control (like Name, address and so on). Because the servers are now switched, the data is lost (at least thats what I think is happening). So all entries in the wizard control are now blank and when I try to read those values, they are null.

View 5 RepliesI am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess). I know the cause for this problem (both tabs uses the same session). I would appreciate if somebody have any solution for this. I am using ASP.NET 3.5/VS 2008/VB.NETI will not be able to use Viewstate since I use a master page and pre-init event where view state is not available.

i have 2 different sites under different subdomains.
www.company.com
and e-order.company.com
i want to have SSO so i have tried to make a global cookie.
my question is :does the global cookie keeps the session variables when i am going from one site to another?
if not how can i pass a session variable for ex. session("userName") from one site to the other on redirect?
I have a main website say www.main.com which is developed in asp.net. We have used forms authetications here.
Now the thing is I have a no of subdomains on the same server say domain1.main.com, domain2.main.com, domain3.main.com etc.
I had put some functionality there. What i want is when i redirect my users to the subdomains user has to log in again.
what are the method where i can preserve the users state in my subdomains also.
I have a DataTable which holds information on truck routes. When the user click on a route it display another table with details about the stop along that route. When they click a stop it shows what items were picked up at that stop. Three separate pages with 3 distinct DataTables. Currently I am storing them in the session. Normally, I would use the view state since the data only needs to live on that page. The reason I use the session is because each page is part of a Master pagelayout. There is an export button in the master page which gets the data in the session and exports it to an excel file. The issue is that when the user goes to the item level detail and uses a quick navigation link back to the route information the data for route is not reloaded into the session, just the page. If the user clicks export it will export the data set from the item level detail even though it is not displayed on the page
