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
What will happen if cookies are disabled in my browser, will the session(sessionid and session variables) still be created?
View 2 Repliesusing ASP.NET 2.0 VB.NET how to detect if the session cookies are enabled?
I know how to detect the cookies in general but you can set IE to block the cookies and accept the session cookies...How to detect this?
if using session variables to store and retrieve information is a bad practice? Let me give you some background:
I am developing a site for a friend of mine, and his site is hosted by Go-Daddy. My feeling is that Go-Daddy is not the best place to host a .NET site, but it is what it is.
After the first version of the site was published and people started using it, users immediately started having session time-out problems and null exceptions when referencing session variables. I researched everything I could and tried everything I could think to do, but I just could not correct the issue.
Then, while doing some testing, I discovered that users weren't individually timing-out and losing their session information, but, rather, all users where timing out at exactly the same time, regardless of how long they had been logged in or what they were doing. So, for whatever reason, the server was just dumping all sessions at random intervals.
At this point I needed to move on with the project so I added a number of cookies to replace the session variables, and everything began working properly.
in a hosted environment, should I avoid using session variables? Is it as problamatic as my research and experience would indicate, or is this simply due to the fact that I am working with a poor hosting company in Go-Daddy?
how to create cookies in asp.net . and how to access them ?
View 6 Repliesi have 3 pages, lets say pageA, pageB and pageC.
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:
Response.Cookies.Clear();
Request.Cookies.Clear();
foreach (Cookie cookie in SessionCookieContainer.GetCookies(new Uri(http://localhost/bla/bla)))
{
Response.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
Request.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
}
//Response.Redirect("../Default.aspx");
Server.Transfer("../Default.aspx",true);
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.

If I run below ASP.NET code, it gives me same output in different post-backs. First Time
Name is = Smith
also After Post-back (Button Click)
Name is = Smith
I feel though I have defined singleton, it should return a new object every time in different ASP.NET post-backs. because once the function "PAGE_LOAD" is completed then there are no reference variables holding singleton object. So there is a change of unloading the singleton class from memory by CLR. that means there is a chance of losing private static reference variable and also single ton object stored. In ASP.NET stateless environment, why is it keeping earlier object in multiple post backs and btw, without having any reference variable to that object. Is this is known danger with singleton in ASP.NET environment?

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)

code for read write cookies in asp.net?
View 1 RepliesI 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:
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+InfoPath.1
In such case, how can I set Cookies to identify that machine?
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
ASP.NET / C#
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.
View 3 RepliesCan 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");
cookie.Value = customer.UserName;
cookie.Expires = expireDate;
cookie.Domain = "lithoman.com";
Response.Cookies.Add(cookie);
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.

View 4 RepliesI am using session to strore code
if (!string.IsNullOrEmpty(Request.QueryString["c"]))
System.Web.HttpContext.Current.Session["Code"] = Request.QueryString["c"];

Instead of session,now I want to use cookies.
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.

[URL}
But i like to be sure about this, and is my code ok?
The first one i run it , he runs the code between the if statemant.
The second one he has a cookie so he doesn't run the code between the if, but, the value of the coockie is null ?
