State Management :: Disappearing Cookie Subkeys - Empty String Returned
Dec 20, 2010
I created three web pages: Page1, Page2, Page3. In Page1, two variables(Var1, Var2) were stored by subkeys(Key1, Key2) in a single cookie. After storing, Page1 was redirected to Page2 by Server.Transfer() as the following code:
Response.Cookies("MyCookie")("Key1") = Var1
Response.Cookies("MyCookie")("Key2") = Var2
Server.Transfer("Page2.aspx")
Similarly, I use subkeys(Key3 ~ Key5) to store three variables(Var3 ~ Var5) in Page2 and then redirect to Page3 as the following code:
Response.Cookies("MyCookie")("Key3") = Var3
Response.Cookies("MyCookie")("Key4") = Var4
Response.Cookies("MyCookie")("Key5") = Var5
Server.Transfer("Page3.aspx")
If Cookies("MyCookie") isn't rewritten by other code, it should return Var1 ~ Var5 respectively to execute Request.Cookies("MyCookie")("Key1") ~ Request.Cookies("MyCookie")("Key5") in Page3. However... Strange things happened, Var1 and Var2 were not returned, but empty string are returned instead.

I am busy building a shopping cart with cookies. I have datalist which I populate from the cookies with a delete button next to each cookie
[Code]....
Now the problem is that when I hit the delete / remove button to expire the cookie, what happens when repopulating the datalist is that it shows the original cookie with all it's values as well as a new entry where all the values are blank.

I want to change the value in a cookie:
HttpCookie hc = new HttpCookie("HiddenColumns");
hc.Value = customView.HiddenFields;
hc.Expires = DateTime.Now.AddDays(365);
Response.SetCookie(hc);
Or this way:
Response.Cookies["HiddenColumns"].Value = customView.HiddenFields;;
Response.Cookies["HiddenColumns"].Expires = DateTime.Now.AddDays(365);
But when I retrieve the cookie value, it is still old, unless I do postback. I don't want to use Redirect.

I have developed an ASP.net project with VB.net and SQL Server 2008.
I have used session variable to store the user id while user login to the system.
The declaration is as follows:
Session("user_id") =txt_user.text
On the first page after login I have displaying the name using this Session value. And the menu also displaying according to the session value.
The code I am retreiving the value is,
dim user_name as string
user_name=Session("user_id")
On my development system everything working fine.
But when I implement the system to live server, the session value is not getting even for the first time.
I don't think this is problem with the code. This is some thing esle..
The implemented computer have Windows XP professional operating system and SQL Server 2008 Express edition datbase.
I have installed framework v2.0 and theIIS version is 5.1

I have a datasource with parameters for the SELECT clause and I want to use an asp:CookieParameter but my cookie has several subkeys. For example, the main cookie is named "teres_soft" and the subkey I want to use is "branch_code" so I get this value using a Request.Cookie("teres_soft")("branch_code"). I can easily set such a parameter if my cookie does not have any subkeys but, is it possible to use a cookie's subkey in the SELECT asp:CookieParameter?

Using VWD 2008
Windows Vista client
Host on Win 2000 server.
Have a Order entry application where create a Cookie to store OrderID when 1st item is purchased. Then go through a series of 3 pages to accept shipping info, etc. When we get to the Payment Method page a button allow user to pay via PayPal. If clicked a call is made to Paypal to log user in. PayPal then redirect back to application page called "PayPalConfirm". When we get back to the confirm page the OrderID cookie is missing!
Here is how I create cookie and set expiration to 1 day: Response.Cookies("OrderID").value = "ABCD" Response.Cookies("OrderID").Expires = DateTime.Now.AddDays(1)
Again, the cookie exist through several pages but when return from PayPal it is gone.

I'm using the following line of code to display the number of users currently logged on:
lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()
I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?

We are using asp.net and 3.5 framework. I have a process that sets the value of a cookie named "mystaffid" in the Default.aspx code behind page. This holds the unique ID of the internal user (intranet). Now when I leave one of the web pages to go to another page in the same website I am getting the error "Input string was not in a correct format. " on the 3rd line below. how the cookie disappears? Also, this is happening in the Page_Load of the master page and I am doing the exact same thing in other pages with the same master page and not getting the error. The cookie is set to expire in 1 day when it is set in Default.aspx.
Dim intStaffID As Int32 = 0
If Not Request.Cookies("mystaffid") Is Nothing Then
intStaffID = Convert.ToInt32(Request.Cookies("mystaffid").Value)
End If

We have a local homepage, which connect to our production security environment. When I need to test my site in test environment, I need to get fresh cookie (not the one that was sent to me via production security service, when I opened IE with local homepage).
I am getting fresh cookie fine in Mozilla; but in IE I always have production cookie, and this disables my testing. What I should fix here?

Very new to ASP.NET and C# (somewhat knowledgable in PHP) I have an ASP.NET web application and need to manage access to pages based on a 'status' stored in a cookie. I would like to use the following code to create the cookie in a login method.
HttpCookie cookie = new HttpCookie("UserCookie");
cookie.Value = "status"; <-- this will be replaced with a variable once its working
cookie.Expires = DateTime.Now.AddHours(1);
Response.SetCookie(cookie);
My problem is that the only place I can put this code where it works is in the global.asax Session_Start method. It simply doesn't work anywhere else. I am checking the cookie creation in firefox options and see the ASP.NET_SessionId created but nothing else (This is all running on localhost).
Is the session status somehow interfering with the cookie creation? Do I need to configure something in Web.config? It would appear that the only time I can create a cookie is on Session_Start. Does anyone have any tips, perhaps I am missing something simple?

My code is as below:

I have a website of online games and I try to count and show the number of the uniqe visitor per game page, by using Cookies only. (if someone visit after 24hr it will be uniqe visitor too)
the problems is:sometimes (I don't know why), not always, it's update the counter colomn of the game, +2 instead +1, and I don't know why, there isn't any "for loop" etc.. maybe is't because the url rewrite? but it work fine if people enter again the colomn will not update again, the problem is that is update +2 instead +1 (see the code at the bottom)this is my algorithm (something is wrong in this algorithm so don't use it):
1. put the query string in variable (the name of the game) - i'm using url rewite.
2. use this variable for select the game Name (and another information) from the database (and for the cookie I will use the game name from the database and not from the query string to avoid from capital letter problems, because cappital letter for the first word isn't good because words like of, to etc..).
3. for each pageload (there isn't postback in the game page) check if the cookie of the uniqe game exists
4. if not exists, create a cookie for the unique game (the name of the cookie and the his value will be same, because I don't care about it, it's only for check if the cookie exist, and I can't use one cookie for all the games because each time visitor enter the cookie will create for 1 day).
4. after this creation of the cookie try to find if the cookie exist (for cheaking if the user didn't disable the option for cookies)
5. if yes update the database column of the spesific game
the code:
In the end of the page_load - (the GameName is the virable of the name of the game from the database and not from the qury string).
[Code]....
and the update function
[Code]....

Our app uses session to keep track of users. We stuff their user id into session on logon. If the browser cache is cleared any refresh to the page is done then the user will see the log out sign - as the app cant get theuser id from session as the aspnet_session cookie wont be present in the request.Firefox works correctly but when I clear the cache on i.e. the session is maintained. The session ID's are the same for multiple requests.how I can debug the app to see what cookies its getting. How do I look at the actual cookie that is passed to .net?

I would like to change ASP.NET session cookie name "ASP.NET_Sessionid" to some other name. I specified <sessionState cookieName="MyCookieName" />. When I use fiddler to view response header, I can see "MyCookieName" with random generated number under cookie section, however, ASP.NET_SessionId also exist there.
