State Management :: Cookies - Storing Max Records?
Apr 6, 2010
I am developing questionare web site, where user has to answer around 55 questions. Its basically a check / uncheck option. So when user submit I store the value in DB.
The issue I am facing is if user selectes all the option, cookie value is lost. I see only 50 records can be stored (Request.Cookies.AllKeys)
Even the SessionID value is lost.Any solution / work around.
I need to store in the client side only. because if the user choose all options and do not submit. The values can be stored in the cookie and later point if he comes back we can read and give to him
We have a scenario where we need to store large tables of data on Session in asp.net page. on a highlevel we have to store following data
1> A table (table 1) with 1000 rows and 8 to 10 columns.
2> A table(table 2) with 500 rows and 8 to 10 columns (actually user can add the data from table 1 to table 2, so as user keeps on adding from table 1 we remove the data and put it in table 2)
3> Another table(table 3) with 1000-1200 rows each having 3 columns.
We are having a webfarm, so we need to store it in either SateServer of Oracle DB,What would be the performance implications of storing such huge data on the server.
One more thing is at any point of time max of 70 -80 people will be accessing our website, so will this cause any performance degradation?
1 . From "pageB", i'm sending some data to "pageA" and and retriving the result with using HTTPWebRequest and HTTPWebResponse classes. I have no problem with this
2. pageA fills some session data, like Session["CustomerInfo"] .
3. After retrving some data from "pageA", I'm redirecting from "pageB" to "pageC".
At PageC, i want to use session variables which i fill at "pageA":
At pageB, i get the CookieContainer of the HTTPWebRequest object and it retrives correct SessionId.
And here is the code that redirects pageB to pageC:
At pageC , Request.Cookies and Response.Cookies are set truly, as i sent them from pageB, but there is nothing in the session. Session.Count is zero. And SessionId is different from the value which is stored in cookies.
In my website I am maintaining cookies for the login so that if I open the browser again then no need to login again.
But when I am switching browser(from ie to ff or viceversa) then the cookies are lost and the user is not identified, I want to maintain them in this scenario also.
I'm working in vb language and I would like to know how to store the values of asp.net controls (textboxes, selected items of combo boxes etc) so that I will be able to display them on a different page. I was using cookies but it's not working.
Page 1
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Response.Cookies("FirstName").Value = txtFirstName.Text.ToString() Response.cookies("Date").value = cboDate.selectedItem.Text.ToString() Response.Cookies("FirstName").Expires = DateTime.Now.AddDays(1) Response.Cookies("Date").Expires = DateTime.Now.AddDays(1) End Sub [code]...
I tried to set a Cookies by Response.Chookies("chookie1") into a user's machine and found difficult to get the Cookies by Request.Chookies("chookie1"). I think that is because the person used various cs(User-Agent) (browser names?). Here are some of them:
We are facing a very strange issue, which is senseless. We have dedicated test server and live server. cookies work properly both on IE and firefox locally. when we deploy it on dedicated test server, It also work their on both browsers. But as soon we deploy it to our live dedicated server, it works properly on IE, but firefox does not remember cookies. Here i want to tell you one more thing that both test setver and live server configurations are same. they both are 64 bit machines. Waiting for ur responses.
Can someone show me what I need to do to allow cookies: I have this code after I "authenticate" the user (my own Login Control, & code to authenticate). If the user checks the "Remember Me" checkbox I am trying to set a cookie with this:
// add 1 month DateTime expireDate = currentDate.AddMonths(1); // set the cookie HttpCookie cookie = new HttpCookie("LithoUserName");
When I go to retrieve the cookie the value is not there. It worked once, then I closed the browser and it disappeared (the cookie was no longer there).I went to GMail & there cookie worked so I am pretty sure the problem is my web.config, but most of the examples for Forms Authentication want you to "authenticate" with Forms Authentication, all I need is for cookies to work. I was able to do this real easy 12 years ago in Class Asp using Visual Interdev, & thought that product sucked compared to Visual Studio 2008 today, but if progress makes a cookie not work then something is wrong. This is not a bank site, or a matter of a life or death, it is just a time saver to sign someone in.
can i get few data from textboxes (like 12 text boxes) and store it in cookies? so the next time the user will not need to type the data again (so the data will place auto in the text boxes for the next times)
In my website I m using third party cookies i.e. when i logged in then I m accepting cookies from third party through javascript.
Now all done well in firefox and other browser except IE. After doing some r & d i found that default settigs from IE doesn't allow accept third party cookies.So after settings "Allow All Cookies" problem is solved. But now my concern is that is there any way that end user do not have to settings manually in IE ?
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 have developed an web application which use cookies to store data. I need to clear cookies on sign out from application.I am new to asp.net. How can i clear cookies.
if cookies are disabled at the clients enviorment, what should we use to store the global data or the sessional data, for example now i use APPLICATION["VarName"]=Value;
To store the data, how is it different from
SESSION["VarName"]=Value;
Also if both dont work when cookies disabled , what is the best approach to store the global data
here i have code for write cookies in computer but i dont know where is store in local pc , i know it write some where b'caz i can read this cookies also but where it save in local pchere is code
'Create a new cookie, passing the name into the constructor Dim ContactId As New HttpCookie("ContactID") Dim PWDID As New HttpCookie("PWDID")
I've begun building a bit of a framework that I wouldnt mind working with. The idea is to create a framework that makes it even easier to create CMS addons (So basically a CMS framework).
One of my goals with this project, was having all modules made within the framework automatically support version without any extra coding.
More to the point, the way that I started building this, many pieces (Lots had to do with the versioning system) became interlinked. A version Object in the code related directly to a Module Object and vice versa, therefore the class definitions for each relate to eac otherh. (So having only the Module object, i could access the versioning object and all of its properties). My issue with this is of course what happens if i have both the module and versioning objects in my code simoultaneously, resulting in having not just duplicates of the data within the code, but (perhaps) infinite amounts, killing the app.
So what im wondering is, what if my modules properties where stored within the cache? Ie if i had the Module object, and it had the property ID -- Then the data for ID would be stored in the cache within the module object. Referencing the value simply retrieves the value from the cache if it exists there, and the SQL database if it doesnt. This way, all instances of the module that may be running at the same time will have access to the same information, at the same time, and hopefully causing it to use less space in total.
I would then add a function, so that if a developer was loading a rarely used module, or dident want to occupy cache space with large amounts of data, then they could just call a Dispose function that would remove the data from the cache.
Does this method sound reasonable? I know this probably isnt what the cache is designed for -- but I cant think of any other way to do this without having an infinite loop of objects referring to each other, or causing huge discrepencies from having different instances of objects referencing values that should be the same, but arent because they are technically different instances.
anybody tell me how can i check session is storing value or not?
actully i am using first time session variable to store datatable gridview but do't know that is saving value or not actully in my grid when user inser first row entry then it is ok when click on new row button then new row generate but previous row value lost.
I have written a property globally on page load i am storing setting some value into that property but on button click i am not able to retrieve the data. Is there any alternate way to save the data other than viewstate or sessionstate. Ex:
Partial Class _Default Inherits System.Web.UI.Page Private s As String Public Property Test() As String Get Return s End Get Set(ByVal value As String) s = value End Set End Property Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then s = "Test" End If End Sub Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click s = "Champ" End Sub Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click MsgBox(s.ToString()) End Sub End Class
