Mvc - Session - User Can Open Multiple Tabs - Browsers?
Aug 9, 2010
I am a bit confused on how ASP.NET session works with my site, when a user opens up the site in multiple browsers, and/or multiple tabs. I see that after logging in with IE, i can open a new tab and not have to log in, and that if I log out of one tab, the other one will redirect to login after I try to do something. I also notice that if I log in with IE, i still have to log in with FF. My question - are session data shared between all of these sessions?
We use windows authentication. User opens our website in tab1 and does some action but with out clicking on save he opens a new tab tab2 and opens the same website again. Now, if the user session in tab1 is active i need to warn users that the he is already logged on to application in some other browser and go to some log out page. But if the user session in tab1 is timed out then he must be able to continue with the website in tab2 as usual, but if he tries to do anything in tab1 he should go to session expired page. I tried implementing it in following way.
I have a hidden field in each page which will be set to unique Id using GUID.NewID(). when user requests for a page the following code is executed.
I have a form that works just fine, problem is that if user leave form open for more than 20 30 min and then click a button on that form the browsers status line shows "Error in page", user then must refresh the page in order for the page function.
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.
I have Menu in my page that it works with linqdatasource.it binds through linq and I created this menu using datalist,and I use linkbutton to show MenuItems.I want to show these items in my page through tab.but I need to display each item in different tab.whenever I click on an item new tab create,and when i click an onother item the previous one stayed open and the current one open in new tab.
In Visual Studio, when I click > Debug, > Start Without Debugging, (with my default browser set to IE), the application starts but it opens 2 IE browser instances. It opens 1 IE instance to start BUT when I close it, it launches another browser instance with the same start page. This bug is repeatable and consistent behaviour, that I can reproduce on-demad in IE.
(In some other minor variations, it seems that depending upon exactly how I start it, it will open 1 browser instance with 2 tabs, each tab having the startup page in it. However, this is not yet repeatable or consistent. It has happened; but, as of now, I am uncertain as the the exact steps to reproduce this particular variation of the anomaly.)
I am using Internet Explorer 8 (IE8).
I am using on Windows 7 32-bit.
I am using Visual Studio 2008 Standard.
I only have 1 startup project defined in Solution properties.
I have all Toolbars And Extensions set to "Disabled" in IE.
I have turned off "Automatic Crash Recovery" in IE.
I am using cookieless session manangement in ASP.NET 1.1. When the session is active and the user uses the same url in a new browser window or a new browser in different machine. since the session is active the url will validate itself. When user open new window with same session, i want show some custom meesage.
how can I open a new window that contain some data without having any menu or tabs in the open new window. Basicaly, I have a linked button that I need to open in a new window that show a box with whatever information I specify without having to deal with any other thing in the open new window. ( no favoites, tools ,status bar, tool bar or links )
Also, can I control the size the location of the opened new window
Just wondering if it is possible to set it so that when you have too many files open in Visual Studio, rather than display the little down arrow icon, it drops the tabs down onto another line?
In my web application, I use an exit button which runs session.abandon to close the session and then close the browser. It does not work with multi-tabs in IE. If I open my application in two tabs, I click on the exit button in one tab which abandons the session and close the tab. But the application in another tab can still work. Is there any way to close the session for this application in all the tabs?
I want to show countdown time in the status bar of browser like: You session will timeout in 40:00 minutes. You session will timeout in 39:99 minutes. I mean it should countdown to 0 and popup a window if user click Popup's Ok button then it should show a redirected page. No ajax support required. I want manually coding therefore I am not allowed to write anything in web.config also.
I have a website built in ASP.net 3.5, using WinForms and AjaxToolKit. I have encountered a lost/corrupt session issue while using Internet Explorer 8.
1. Login, Redirect to Landing, Logout - WORKS AS EXPECTED 2. Login, redirect to Landing, Close Window, Open Window, Logged-in already - WORKS AS EXPECTED (remember me enabled by default in code)
1 IE8 Browser, 2 Tabs -------------------------------------- 1. Login, Redirect to Landing, Open new tab, paste Landing page URL, Landing renders. - WORKS AS EXPECTED - Logout from Tab 2, Tab 1 logs out after AJAX update. - WORKS AS EXPECTED - Login from Tab 1, Redirects to Landing, then Redirects back to Login page - ISSUE

This issue seems to only happen when I have multiple tabs open,or multiple rwssers open.Firefox and Chrome does not reproduce this issue and works as expected.How do I make sure the Cookie/Session is being handle correctly in IE8?

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.
I have a page where I display ASP.NET charts. There are two types of charts and I felt the need to separate them to some extent which I did by using a submenu which looks like this:
Charts > Goals Charts > Reconciliation Charts
Clicking on either of the two chart links will take you to the same Charts.aspx page, but with the query string "Goals" or "Reconciliation" respectively. On the page load of the Charts.aspx page, I receive the query string into a session variable and create the correct charts based on that value. All of this works fine.
The problem I'm experiencing occurs when I open up a new tab in IE/Firefox. Here is the series of events I'm experiencing:
- In the original tab, I will click on the "Goals Charts" hyperlink which loads the Charts.aspx page with "Goals" as the charts type session value. The other controls on the page needed to produce "Goals" charts (eg. drop down lists, etc) are displayed correctly ie. the "Goals" version. At this point, I haven't done anything in this tab except for loading the Charts.aspx page from the "Goals Charts" link.
- In the original tab, I right click the "Reconciliation Charts" link and opt to open in a new tab (I just tested and the same thing appears to be working if you opt to open in a new window as well). When the new tab loads the Charts.aspx page, it loads with the query string "Reconciliation" which it stores in the session variable. So at this point I would expect to have two different, independent tabs: the original tab on the "Goals Charts" track and the second tab on the "Reconciliation Charts" track.
- This is where the problem occurs. I would expect the original tab/window to create a "Goals" chart when I make a selection using the other controls and I would expect the second tab/window to create a "Reconciliation" chart. The problem, however, is that when I go back to the original tab/window - the one which should be a "Goals" chart and which should have "Goals" stored in the session value - when I proceed to create a chart, it's a Reconciliation chart that is created.
Somehow, even though I'm in a different tab or window and I am navigating the site seemingly independently of the other tab/window, it seems to be carrying the most recently populated value from the session variable for both tabs/windows.
I'm trying to get a page working using a tab container and multiple tabs. So, I created a new blank page and pointed it to my master page. The master page has two content panels within it.
I'm adding the tab container in the top conent holder, but when I go to view the page, I get an error. Below is the error followed by the code.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
