want to know, if the developer is logging out of the website , when .Net Custom Error pages are displayed. If the browser's back button is pressed, previously logged-in page is displayed again. Is there any session going on. How to remove all relevant cookies on logout.How to resolve this
View 1 RepliesI want know, If an error has occurred and website is redirected to the Custom Error Page and is also logged out. If back button of the Mozilla browser is pressed, previous logged in page is displayed. I have also used
1.
Response.Cache.SetCacheability(HttpCacheability.NoCache);
2.
Response.Cache.SetExpires(DateTime.Now);
in Page_init on Custom error page. Also set the values of .ASPXAUTH and other cookies to 1 but again page is not going to the Login Page. These cookies could also not be removed.
My page is logging out in 20 minutes. I want my page should not be logged out for 60 mins.

View 3 RepliesMany web applications use sessions to check the logged in status of the users. Is there a better approach to check the logged in status instead of using session state?
I'm looking at a pure ReSTful approach where is no session state at all. This may make more sense in an mvc application rather than an asp.net application.
I have a requirment , my site is using Formauthentication cookie to validate the users , so once the same user is logged in to another browser again ( same Machine or different) then I need to log off the first site and need to allow the second one active.I am thinking to implement this by storing a uniqueID in the DataBase user table .Once the user Logs in then I will store this ID in to the database and for each request I will check whether the ID is same or not, once the user logs again in to another browser then the Unique ID will get generated again and store (update the previous one) to the user table so that the request from the fisrt instance browser will fail to validate and kick out to login Page.this procedure will reduce the performance since all the time it need to intract with DB, so is there any other possible way to Implement this scenario with out using BD - but using formauthentication cookie.
View 1 RepliesI have created a simple website in asp.net using forms authendications but when I publish my website in IIS 6 on a Windows Server 2003 machine it keeps the users logged in for ever even though I have set the web.config to expire after 30 min. My website has 2 pages a login.aspx and a home.html. When I run the website in my development machine using the ASP.NET Development Server I have no problem the website works as expected meaning the users can not access the home.html unless the have been authendicated by the login.aspx page.
Also once loged in, after clearing the browser cookies the web site asks for login again which is again the behavior that I am trying to accomplish. However once the website is on IIS does not take in account the authendication that I have set up on my web.config. What is overriding my web.config? Do I need to make some changes to the global configuration of IIS?
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 am working on a asp.net 3.5 app. In the Global.asax in the Application_Error method, I am logging everthing to ddatabase (log4Net).
I have a session limit of 20 minutes. What happens when the user hits that limit and then clicks on the Submit Button of the app. ?Will that generate any exception? and will that exception be logged into my database as I am logging all exceptions in my Application_Error method.
I think my subject line explains my problem in a nutshell.. I have a login page, I login like I should and everything works.I logout and when I type/paste the address to the page, in the address field, I still reach it just like if I was still logged in..The page I type in the address field is in a subfolder, only suppose to be able to be reached by logged in users and in this folder,ith it's own web.config-file:
<?xml version="1.0"?>
<configuration>
<system.web>

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users. Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies. In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage sessionAs for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was. This seems to work well for us. It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.What's happening is that certain users are being logged out after just a few minutes. We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out. We do not know why the HttpContext.Current is null, and I understand there are many reasons that may occur. What I'm trying to figure out is, is there any way to re-establish the context once it is null? If not, is there anything I can do at this point other than have the user login again? We're also trying to figure out a better way of managing user information (preferences, roles, flags, history, etc), but everything needs context to use, right? Cookies, sessions, cache, etc. all require a response or request, correct? hope this makes sense, because I really need help with this. I've searched the forums here, and found many posts about HttpContext.Current going null, but not a lot of solutions for this...
View 14 RepliesI have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
I have created a matser page with a two radio buttons, text box and a button. Whenever user sets some values to these control and clicks the button, i will navigating him from one content page to another based on the data he has entered. The problem is after the content page load, the values selected/given in the controls(radio button, text box) are getting cleared.
Is there some way to maintain the values ?
i have a form on page1.aspx with several controls (textbox, dropdownlist, etc).on Page1 PageLoad event i load data from database and performe databinding.From Page1 a user can, by clicking a specific button, move to Page2.aspx to insert some details and, after saving details, he returns to page1.
if save changes are made on control on page1 before save them to db, obviously, these are lost on return from page2 (because are reloaded on pageload from db).How can i save control status between pages round trip?
I am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.
