View 4 RepliesI have a web application (SnapshotServer) which uses a WebBrowser control to take a snapshot images of a web page.
I use a WebBrowser control within SnapshotServer to navigate to a entry page of a secure web application (ImageHost) and then redirects me to my required page.The ImageHost application is protected by FormsAuthentication, which uses cookies. The entry page I navigate to takes care of logging me in - which will create an Auth cookie.
Once a response is generated from the ImageHost, I convert the result within the WebBrowser control to an image.
Issue:
When I run SnapshotServer on my PC (Windows 7, IE8), using IIS7, and navigate to ImageHost on my development server (Windows 2008 R2, IE8), the result is as required - I'm logged into ImageHost and redirected to the page I want an image of. When I run SnapshotServer on any Windows 2008 R2 server, using IIS7, and navigate to ImageHost on my development server (Windows 2008 R2, IE8), the result is not as required - ImageHost fails to log in - so my image is of the login page. The reason it fails to log in is that it isn't creating an Auth cookie.
So I'd like to know if anyone can tell me why the WebBrowser control, when run from a Windows 2008 server, cannot create cookies.
The Request.Browser.Cookies property (of type bool) attribute stores information whether client's browser supports cookies and whether or not they are enabled.How reliable is the property Request.Browser.Cookies? Is it guaranteed to be correct ? Or should I rather implement redirection technique suggested by Software Monkey in this question?Please note: This in not a question "are cookies reliable" ? This is a question: "Is the information whether users browser accepts cookies reliable?"
View 2 RepliesWhat will happen if cookies are disabled in my browser, will the session(sessionid and session variables) still be created?
View 2 RepliesIt's weird, my firefox has cookies disabled, yet I am still able to retrieve the cookie.
Code:
protected void Page_Load(object sender, EventArgs e)
{
Response.Cookies["a"].Value = "1";
}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = Request.Cookies["a"].Value.ToString(); //it returns value
}
Why is this?
This thing has just came to my head and I wanna share it.Note : I could easily test it but I am being lazy here to see if anybody has ever experienced something like that before.Let's assume that I have a web site which built-in membership structure of asp.net has been implemented on. What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?

View 3 RepliesI want to create a custom attribute to check if the browser has cookies and javascript enabled. I'm guessing I would create a ActionFilterAttribute that would redirect to a controller action to load a page to check cookies and javascript on the client side. If they are enabled then it would redirect to the desired action, otherwise display an error message. Is this a correct approach or is there a better way to do this?
View 1 RepliesAs we know that closing a browser will delete cookie if the cookie does not set an expired date. However, I want to set an expired date to all of my cookies and also delete them when browser closed.
View 2 RepliesI'm handling cookies using JavaScript to store some values in my asp.net web application.I use document.cookie to save some values (converted into a lengthy string). But i want that value to be accessible across all the pages in my application.When i try to get that value from a different page, i get the values pertaining to the document in the current URL.
In short i save the value in the cookie in http://myapp/doc1.aspx and want to retrieve it in http://myapp/doc2.aspx
So is document.cookie is pertaining to a single document scope? How can i save/read cookies across the site?
Update.This is how i get and set cookies
function getCookie(c_name)
{
try{ [code]...
But i'm getting different values for the cookies in different pages.
I have been experimenting with code that will clear all of the cookies in an HttpContext.Response.Initially, I used this:
DateTime cookieExpires = DateTime.Now.AddDays(-1);
for (int i = 0; i < HttpContext.Request.Cookies.Count; i++)
{
HttpContext.Response.Cookies.Add(
new HttpCookie(HttpContext.Request.Cookies[i].Name, null) { Expires = cookieExpires });
}
this will error with an OutOfMemoryException because the for loop never exits - each time you add a cookie to the Response, it also gets added to the `Request.
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?

i need to get the Browser version, type of the user. i need the short name not the long one.
at the monent i have this:
browser = Request.ServerVariables("HTTP_USER_AGENT") that retuens this:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249
i need only (Chrome/4.1.249), (MSIE 8.0)...............
plus i would like to get the operating system too
I have a web application that runs via IIS 7 what i want to do with the application (Asp.net with C#) is only load if the browser is greater than IE9, or greater than or equal to Chrome27 or greater than or equal to firefox19.
How to do this or areas i should read to do such a thing?
How to handle cookies in asp.net?
View 5 RepliesOn my content page I have the code (in page_load):
if (Master.pageAction == "remove")
{
int removeProductID = int.Parse(Request.QueryString["ID"]);
int removeOptionID = int.Parse(Request.QueryString["optID"]);
Master.myBasket.removeFromBasket(removeProductID, removeOptionID);
//Response.Redirect("viewBasket.aspx");
}
The function remove from basket is defined as:
// Removes item from a basket
public void removeFromBasket(int itemsID, int optionsID)
{
Page myPage = (Page)HttpContext.Current.Handler;
this.setCookieString("");
myPage.Response.Write("done");
}
And it calls:
// Sets cookie date
public void setCookieString(string cookiesData)
{
Page myPage = (Page)HttpContext.Current.Handler;
HttpCookie basketCookie = new HttpCookie("basket");
basketCookie["items"] = cookiesData;
basketCookie.Expires = DateTime.Now.AddDays(7d);
myPage.Response.Cookies.Add(basketCookie);
}
I use the setcookiestring function on other pages and it works fine, but this function (removing from the basket) isn't setting the cookie! It is writing "done" to the top of the page, so the functions are executing.
No warnings, no errors, it's just not updating the cookie.
I want to use session object in my web app.I want to store some cookies too(Some custom informations) .How can i use both without the URL not being modified like [URL]
In my ASP.NET page,I am setting some session variable
Session["customerId"]="Some name";
Then i am trying to set some value in cookie
[code]....
In this page now i can access the sesion variable values,But when i m being Redirected to another asp.net page, I am not getting my session values there.Its seems like Its being lossed.
I would like to encrypt cookies in ASP.NET.
I have followed the method in this article, but it has the drawback that is uses reflection on an internal method. This has caused it to be flagged in a code review -- it is not future-proof as the internal implementation may change.
Is there a method with identical functionality which doesn't require using encryption on internal methods?
I am using .NET Framework 3.5 SP1 (Assume I cannot change framework versions)
I configure IE8 to block cookies.
View 1 RepliesMy application at mysubdomain.mydomain.com needs to set a cookie that contains some user session information.
They log in at a https page. We authenticate them and set some session info in a cookie.
We do this in a helper library that takes in the controller context
contextBase.Response.Cookies[CookiePayload.CookieName].Value = encryptedTicket;
contextBase.Response.Cookies[CookiePayload.CookieName].Expires = cookieExpires;
contextBase.Response.Cookies[CookiePayload.CookieName].Domain= ConfigHelper.CookieDomain;
contextBase.Response.Cookies[CookiePayload.CookieName].HttpOnly=true;
We do a quick redirect in the controller (to a non https page):
this.ControllerContext.HttpContext.Response.Redirect(redirectTo, false);
return null;
The cookie appears in the response (according to firebug's net tab).
But neither fireforx nor ie send the cookie on subsequent gets.
We are setting the cookie domain to mydomain.com even though the site is mysubdomain.mydomain.com. Skipping the redirect command has no effect, nor does changing the cookie value.
I'm trying to do some simple stuff, I've already looked at the examples through the web and I'm not sure of what I'm doing wrong It's a unit test that i'm doing to test some functionality that later will be performed by some different devices Basically I'm creating a webrequest to my site, which returns a set of cookies, which we later on need. Then I want to create a new webrequest, using the returned cookies from the first response, but when i'm reading that info, the cookies are empty
var request = (HttpWebRequest)WebRequest.Create("http://localhost/bla");
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "GET";
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(originalResponse.Cookies); // originalResponse.Cookies has several cookies needed by "bla"
var response = request.GetResponse();
In another place... (inside "bla")
HttpContext.Current.Request.Cookies // this is empty
I know how to get a cookie on the code behind a page, but am trying to do the same thing in a class (instead of the code behind) without any luck.
Basically here is the situation:
There is a cookie already set (let's call it cookieX) and I need to retrieve the cookie within a class.
Once I get the value here is the logic I need If cookieX.value <> 1 OR cookieX.value IS NULL Then Redirect the User to PageX End If
So the overall question is how do I create a class within VB to read a cookies value, and then what goes in the class and what goes on the code behind the page? Essentially the plan is to check for the cookie on multiple pages, hence I am trying to separate the code into classes as much as possible.
