I need to clear all sessions at the end of my application, to many to list individually.
So I have found the following ways, but which is best?
Session.Clear();
Session.Abandon();
Session.RemoveAll();
And then the specific way
Session.Remove("variable");
I have 4 webpages. In those pages, i am using session variables,viewstates,cookies. I am passing session variables,viewstates to different pages. Now the problem is sometimes i am getting the old cookie values or session values. I want to clear all these things when i close the browser or if i open a new tab of browser.

I want to clear all the Session variables.
i am trying to collect 2 variables from one hyperlink, and use those variables in the page_load to set as session. but i don't know how to collect those 2 variables
such :
<a href="javascript:;" onclick="wsChangeColor('mainData', '#FF0000','#FFE4E1');return false;" title="Change color" id="red">1</a>
i would like to collect '#FF0000','#FFE4E1' or direct set '#FF0000','#FFE4E1' to string then send to pageload, how can i do this by only clicking on it ?
I have problem is that when i force to clear session so it remove all session on to server. i mean i open website at 2 systems and one system logout website so 2nd automatically logout.i dont know when is the problem. i m using Session.Abundent for current session.but it clear all.
View 2 RepliesFor some reason it seems as though variables that I declare in javascript sometimes persist themselves across applications even when I do a response.redirect. I thought that a response.redirect would clear them out.
View 1 RepliesWhat is the difference between Session.Abandon() and Session.Clear() in ASP.Net?
View 1 RepliesIs there a difference between Session.Clear() and Session.RemoveAll()? The descriptions and documentation pages seem to say exactly the same thing, but I am assuming there must be some reason for creating two functions, right?
View 2 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.

There are reams of info out there about things causing InProc session to drop session objects, but that's not what's happening here. We're missing individual variables within stable InProc session objects, and are not sure whether they're not being written or being lost after a successful write. I've confirmed with WinDBG that the sessions are live and contain some, but not all, of the data written to them.
Guid g = System.Guid.NewGuid();
this.Context.Session.Add(g.ToString(), result.ImageData);
output.Write("<img src="display.aspx?id=" + g.ToString() + "">");
This code is pretty straightforward, and it works flawlessly in Test. In Production, under heavy load, though, it fails ~1% of the time. If Mr Smith visits the site and attempts to display 4 pieces of image data, 2 of them might be saved in his session and two of them be lost. The InProc session object for Mr. Smith exists. The traffic logs show he clicked 4 times, each with a different id param. But there are only 2 guids in his InProc session object, instead of 4. The 2 session objects we did capture do correspond to 2 of the id's shown in the traffic log (his 1st and 3rd clicks.) The traffic logs for his 2nd and 4th clicks, though, show a guid id that's not in his InProc session object.
Lines 1&3 of the above code obviously worked for those 2nd and 4th clicks, or he'd not have had the id in the URI for him to click. Line 2, however seems to have failed silently in some way. If any exception had been thrown, I'd expect we'd not ever have arrived at line 3. I can't see any way for the user to receive the guid id, but the session to fail to have it. The other possibility is line 2 worked successfully, but the variable later disappeared, how I cannot even imagine.

We're running a web farm, but users constantly return to the same server. I'm researching now whether there's any way users might be slipping off to the other server.

I really appreciate any ideas and inputs on how and where to clear the session object
View 8 RepliesI have just added the following to the very last page of my application.
[Code]....
And then i have this on each of the pages before the last, within my Page_load:
[Code]....
I have different sessions thruout the application process, but this one session is only set at the beginning of the process and once i kill it on the last page, any attempt to hit Back or trying to access any page directly without first starting, i need to force them to the beginning, what am i missing or doing wrong?
sessID is set on page 1 and is available until you get to the last page. Where i added the Session.Abandon(); Now if i get to the last page and hit back before the refresh occurs, im able to go back, but the page comes up with null reference for other sessions that are obvisously cleared / killed with the abandon. So i should have to check for each session should i? I mean if the abandon killed them all, then checking for the main session should be enough right?
I am using master page and i use session id to identify coming user before navigation
i have a link button to logout ..this link button only will navigate to login page
once navigated if i click back i am still able to browse the page
clickin logout button not cleanin the session? how to avoid page click back?
or how to clear session id when user click logout?
I have multiple sites with main and subdomain. all doing one same method for the login. login is done with the multi domain cookie but there is problem with the logout. I'm using cookie and session for that state.
When ever I logout form the any domain. I should logout form the all domain.
(Like yahoo or google)
As per my method , My all domain have logout page which has code
[Code]....
and main site(www.domain.com) have
[Code]....
So what can I change in this code to do the Logout process for the all subdomains.
I have a report parameter page which contains many pop up windows for the parameter selection. For example, for driver , there is a pop up window called driver.aspx which contains a listbox that contains list of driver's name.
Now, for each of these pop up windows, i am passing the values of these windows as a session value.
Now, when a user logs in the system, there are many parameter pages for different reports which commonly share the same pop up windows if the parameters are same for different reports.
The problem now is,a user selects 10 drivers for report 1 and runs it. When he goes to report 2 and runs the report, the report 2 takes only those 10 drivers as the driver parameter value.
It means, the error can arise on the system because he may forgot that he have selected 10 drivers for previous report 1. User will not have time to recheck each previous selected values of different paramaters.
What i want is, when a person moves from one report page to another, i want to clear all the session values and adjust it as default for the new report .

View 3 RepliesAm trying to design login page for my website and I am looking for methods other than forms authentication. The way in which I am trying is to have a table in the database that stores user information and check for the user validity.
The point where I get struck is how do i set cookies and session variables and how will I carry it through out the system. Can anyone tell/suggest me where I can relevant material so as to move forward. And also is my idea of negating traditional forms authentication and going for a model I described, is it good also does any other better method exist?
I want to password protect an area of a website by a login/registration form.
I'm using session variables to check wheter the user is logged in or not. I already have a database with users/passwords... so I thought that the membership approach wasn't an option... (correct me if I'm wrong)
in the constructor of the controller of the area I want to protect I've added the following:
[Code]....
but this throws an error:
Server Error in '/' Application.

I am working on an asp.net mvc app.Right now I am looking for the best solution to access session variables.
Is it oke to make a static class to get session variables, like:

And so on for other session variables.Is it allowed to access session variables in static model classes ?
In my .NET web app, I keep basic user info in a user session object. I also usually keep a director class in the session; which is basically just has info about whatever thing it being worked on on that screen (like a customer id).
I am trying to keep from adding a ton of sessions. I also want to make sure at any given time ONLY the sessions that are necessary are in memory.
This means I need an effective way of managing my session variables.
