How To Find The Cookie In IEs Cookie-store
Jun 14, 2010
I am a bit baffled here; using IE7, ASP.NET 2.0 and Cassini (the VS built-in web server; although the same thing seems to be true for "real" applications deployed in IIS) I am looking for the session-id-cookie. My test page shows a session id (by printing out Session.SessionId) and Response.Cookies.Keys contains ASP.NET_SessionId. So far so good.
But I cannot find the cookie in IEs cookie-store! Nor does "remove all cookies" reset the session (as it does in FF)... So where - I am tempted to write that four letter word - does IE store that bloody cookie? Or am I missing something? By the way there is no hidden field with a session id either, as far as I can see. If I check in FF there is a cookie called ASP.NET_SessionId as I would expect. And as mentioned above deleting that cookie does start a new session; as I would expect.

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'm trying to use a webservice that first expects the clients to login, to retrieve a cookie to re-use.
This is done through a login(string user, string pass) method on the webservice.
Doing this through a browser works fine, we get a cookie, and we can see the cookie via Fiddler or whatvever proxysniff thingy.
Time to do the same in ASP.Net, so we use the WSDL and generate a nice proxy class, and it works fine to call the login() method, but Never Ever does a cookie get set !
I already used the "cookiejar" technique - which means i create an instance of a CookieContainer and assign it to the proxyclass like this;
var cookies = new CookieContainer(3);

I'm using session to store C# object but my session is expiring regularly.
I've given 540 minutes for session timeout. ( <sessionState mode="InProc" timeout="540"/>)
Now I want to use cookie instead of session to remove this timeout problem.

give me an example (or point me in the right direction) on how to store custom data in an ASP.NET Membership cookie? I need to add some custom properties like UserID and URLSlug to the cookie and be able to retrieve the information in the same way one would retrieve the Username.
Edit:
I used Code Poet's example and came up with the following.
When I set a breakpoint at Dim SerializedUser As String = SerializeUser(userData) the value of userData is right. It has all the properties I expect it to have.
The problem I'm now running into is that when I get to Dim userdata As String = authTicket.UserData (breakpoint), the value is "". I'd love to figure out what I'm doing wrong.
Here's the code.
Imports System
Imports System.Web
Imports System.Web.Security
Namespace Utilities.Authentication
Public NotInheritable Class CustomAuthentication
Private Sub New()
End Sub
Public Shared Function CreateAuthCookie(ByVal userName As String, ByVal userData As Domain.Models.UserSessionModel, ByVal persistent As Boolean) As HttpCookie
Dim issued As DateTime = DateTime.Now
''# formsAuth does not expose timeout!? have to hack around the
''# spoiled parts and keep moving..
Dim fooCookie As HttpCookie = FormsAuthentication.GetAuthCookie("foo", True)
Dim formsTimeout As Integer = Convert.ToInt32((fooCookie.Expires - DateTime.Now).TotalMinutes)
Dim expiration As DateTime = DateTime.Now.AddMinutes(formsTimeout)
Dim cookiePath As String = FormsAuthentication.FormsCookiePath
Dim SerializedUser As String = SerializeUser(userData)
Dim ticket = New FormsAuthenticationTicket(0, userName, issued, expiration, True, SerializedUser, cookiePath)
Return CreateAuthCookie(ticket, expiration, persistent)
End Function
Public Shared Function CreateAuthCookie(ByVal ticket As FormsAuthenticationTicket, ByVal expiration As DateTime, ByVal persistent As Boolean) As HttpCookie
Dim creamyFilling As String = FormsAuthentication.Encrypt(ticket)
Dim cookie = New HttpCookie(FormsAuthentication.FormsCookieName, creamyFilling) With { _
.Domain = FormsAuthentication.CookieDomain, _
.Path = FormsAuthentication.FormsCookiePath _
}
If persistent Then
cookie.Expires = expiration
End If
Return cookie
End Function
Public Shared Function RetrieveAuthUser() As Domain.Models.UserSessionModel
Dim cookieName As String = FormsAuthentication.FormsCookieName
Dim authCookie As HttpCookie = HttpContext.Current.Request.Cookies(cookieName)
Dim authTicket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(authCookie.Value)
Dim userdata As String = authTicket.UserData
Dim usersessionmodel As New Domain.Models.UserSessionModel
usersessionmodel = DeserializeUser(userdata)
Return usersessionmodel
End Function
Private Shared Function SerializeUser(ByVal usersessionmodel As Domain.Models.UserSessionModel) As String
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream
bf.Serialize(mem, usersessionmodel)
Return Convert.ToBase64String(mem.ToArray())
End Function
Private Shared Function DeserializeUser(ByVal serializedusersessionmodel As String) As Domain.Models.UserSessionModel
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream(Convert.FromBase64String(serializedusersessionmodel))
Return DirectCast(bf.Deserialize(mem), Domain.Models.UserSessionModel)
End Function
End Class
End Namespace
Here's where I create all the magic. This method is in a "BaseController" class that inherits System.Web.Mvc.Controller
Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
If User.Identity.IsAuthenticated Then ''# this if statement will eventually also check to make sure that the cookie actually exists.
Dim sessionuser As Domain.Models.UserSessionModel = New Domain.Models.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User)
HttpContext.Response.Cookies.Add(UrbanNow.Core.Utilities.Authentication.CustomAuthentication.CreateAuthCookie(HttpContext.User.Identity.Name, sessionuser, True))
End If
End Function
And here's how I try and retrieve the info.
Dim user As Domain.Models.UserSessionModel = CustomAuthentication.RetrieveAuthUser

I have an application running ASP.NET. I have different domains and different sub-domains. I want the domains to share session with their sub domains.
For Example, the following domains access this application:
[URL]
If a user goes to www.example1.com and print.example1.com, I want it to use the same session. If the user were to go to www.example2.com and print.example2.com, I would want it to use a different session than the *.example1.com.
The way I used to handle it was a hack in page_load that works perfectly in IIS6:
Response.Cookies["ASP.NET_SessionId"].Value = Session.SessionID;
Response.Cookies["ASP.NET_SessionId"].Domain = SiteUtility.GetCookieDomain();
(SiteUtility.GetCookieDomain would return .example1.com or .example2.com depending on the url of the request) Unfortunately, this no longer seems to work for iis7. Each subdomain/domain a user goes to, the user gets a new session cookie.
I then found the web.config entry: '<httpCookies domain=".example1.com" />. This works great for sharing session cookie between example1.com subdomains. Unfortunately, this completely screws up session state for *.example2.com.

I try to create a persistent cookie to store a preferred language on our website, but it doesn't work.
So, to isolate the problem, I created a new website, with a blank page and with the code behind bellow. If I click the button, the page post back and I get this:
"Cookies expires: 0001-01-01 00:00:00 value: 10"

When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
[code].....
I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.
Scenario:On Page_Init() on code behind. I create a cookie using Response.Cookie.Add(new HttpCookie("MyCookie", "cookieValue"));.
On Client side, I'm trying to read the cookie saved from code behind on page load using the snippet above, but it returns undefined

I have a very simple page with the following logic:
protected void Page_Load(object sender, EventArgs e)
{
if (null == Response.Cookies["UserSettings"].Value)
{
HttpCookie cookie = new HttpCookie("UserSettings");
cookie.Value = "The Big C";
cookie.Expires = DateTime.Now.AddDays(10);
Response.Cookies.Add(cookie);
}
else
{
// got here
}
}
I set a breakpoint in both the if and the else and the else break point never gets hit. The if statement gets hit every time. What could be wrong here?

In javascript alert(document.cookie); does not show the .ASPXAUTH Cookie although a sniffer is showing it,
I need it because I have an AJAX Request to the server, the request should not take place when the user is already logged in,
if I cannot check .ASPXAUTH for security reason, what I should do to check whether the user is already logged in.

I'm reading through the info here: [URL] I have a question about how cookies work.
I am creating a series of web pages where the user follows steps in a tutorial. I want to track in a menu that the user has completed a step. It seems cookies would be the best way to do this. My question is, when you create a cookie and you need to write to the cookie at a later time, does it write to the existing cookie or does it create a new cookie with the existing name? In other words, if I initially create the cookie and set all steps viewed as false, then when they complete a step I go back to the cookie and set a step to true, does this actually write to first cookie or write a new one?

Assume we have three different ASP.NET web applications in our intranet, that all of them have a login page and after authenticating user create a cookie for authenticated user. Is it available to have one page as a login page and create that three application's cookie from here and then redirect user to demanded application?

I know that you can't edit incoming cookies. I have a cookie that I just need to read..nothing more but I have a need to remove some characters from its value so that I can parse it. How can I do this? I don't need to send the modified new cookie back in the response, it's just for my server-side consumption and then that's it.
Updated:
figured it out:
HttpCookie facebookAuthCookie = HttpContext.Current.Request.Cookies[facebookCookieName];
string cleanValue = facebookAuthCookie.Value.Replace(""", string.Empty);
HttpCookie cleanedFacebookAuthCookie = new HttpCookie("cleanedFacebookCookie", cleanValue);

We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed."
We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble.

I'm surprised i couldnt find any answers.
How do i set my sessionid in my cookie to expire at the end of session? (when the browser closes or the user has been inactive for a period of tie).
The two solutions i found were
(httpcookie).Expires = HttpContext.Current.Session.Timeout
Which gave me a compile error so i dont know if the user checked his code before posting. And the other was to set the expire date to 1 day ago which my gut says is wrong. How do i do this?

How do I set cookie expiration time in C#?
I want cookies to expire when the browser is closed. I found in many blogs that giving a previous date as the expiry date will cause the cookie to automatically expire, but that is not working in my case.

I say until you log out, session times out or you close the browser. But am I right?
I had an interview today and the interviewer wanted to know if I log into a page and closes the browser (without logging off), what happens to the session.
I said that the session will be orphaned. He says no - because their users are able to connect back to the session by just opening up the browser (using a cookie only). I told him that's a persistent cookie - not a session cookie. And I said that if that's the cause, there is nothing preventing the user from exporting the [persistent] cookie to a another computer and starting the session on that computer.
At first he said you can;t export a cookie but when I explained how, he said that he'll look but since many many people including 2 architects came up with the design, it is unlikely they are all wrong.
