I'd like to maintain a session state per browser tab.
Is this easy (or even possible) to do in ASP.NET?
Example: A user hits Ctrl-T in firefox 5 times and visits the site in each tab. I'd like each tab to have its own session state on the server
In my website, when user logged in, I maintain his/her username in a session but when user opens another tab and use the same website at that time session doesn't work.
For Example: User logged in with his/her details in my website and than when he open another tab of same browser and browse same website at that time it doesn't maintain session for that user.
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
[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.
I have to maintain session of two users on a sigle page.And the path is. UserPath:
1.User logins with his credentials((We retrive their credentials from login table) .
2.He invites some of his friends for a birthday party.
3.And send an url link to share some of the gifts with them in which gifts are provided in Share.aspx page.
4.Userlogouts.
Invites path:
1.Invite logs in with his credentials(We retrive their credentials from invites table).
2.He is directed to go to Share.aspx and list the items he require.
3.And he logs out.
Now i have problem in maintaining session for both the user and invite. How can i maintain the session so,that the user can identify a particular invite from the list of invites an his chosen items.

View 5 RepliesI am using master page.
(1) to maintain the state of the treeview without storing it in session or view state or
(2) I am binding the treeview control dynamically from a xml. Even if I use session state is ther any option to use it without using SelectedNodeChanged event because when u click the treeview node , first master page will postback for this event and then the child page and then again the master page will post pack (as the child page has inherited the master page). So here in this case we are posting the master page twice and it is reducing the performance.
I'm not sure if this is an error or is the right work mode for sql sessions.
I'm working now with Windows 2008 R2 Web Ed. and SQL Server 2008 Web Ed.
When I close my browse and open again a new browser window I need to login again in asp.net application and a new session is created in the sessions table in sql server.
It's this normal? I remember that with Windows 2003 and SQL 2005 this doesn't happend. When I closed my browser and open inmediately a new browser window my session was retained and I could continue working without relogin.
I have a website live in asp.net
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.
Physican is accessing data for patient #1 using ASP.NET Web site with backend SQL Server database. Session state is used to persist some patient information. At the same time, he checks his email and clicks a link in the email that launches the same Web site to check on a communication concerning patient #2. In IE8 these two instances of the application share the same session id. If physican responds to communication concerning patient #2 and returns to patient #1, he will now be accessing data for patient #2.
I know about framemerging etc. but how can I launch a new browser session from the hyperlink in the email without closing or stepping on the http session for patient #1 and without having to resort to cookieless sessions?
I 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.
View 2 RepliesHow to keep the session variables even after closing the browser?
Everytime I close the browser, I lose all the session variables.

I tried to save record on tab #1, facing the problem of session gets over written.I had to check some vaules on OnInit and OnInitComplete event. But I get here wrong values in session.
How to get unique session id that generated same for all browser tabs and different and always unique when we close and open new browser in asp.net code.
View 2 RepliesI want to ensure a user isn't editing the same form data in two different browser tabs or windows (of the same web browser instance). The intention is to stop the user from accidentally overwriting their own data as they continue through a very long form process. On the server, ongoing data input through the screens is collected into the Session.
Assume for any browser, all tabs and windows run in the same instance of it (i.e. not each in a separate process). Obviously the browser tabs and windows share the same cookies in this scenario so cookie modification seems out of the question for viable solutions. This is also the reason they are sharing the same session state.
Considering that the form is already created and this is one of the final touches, how can I use ASP.NET, hopefully easily, to oversee this "feature"?
I receive the error message "Error: Your session has expired. Please refresh your browser." When I export a table in ASP to Excel. I know for a fact that the correct data to export exists. Everything works fine except for this error message. I don't see how the session on a browser could run out in a matter of the one second it takes for the Excel file to pop up

Now will this Session["Cart"] value which is washing machine here be unique to diff customers?

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 ..
