i am creating cookies with following lines:
HttpCookie userid = new HttpCookie("userid", objUser.id.ToString());
userid.Expires.AddYears(1);
Response.Cookies.Add(userid);
Now How to make it persistent?
Because if I visit the same page again after closing the browser, I'm unable to get it back.
I want my cookie to disappear when the user closes their brower-- I've already set some promising looking properties, but my cookies pop back to live even after closing the entire browser.
HttpCookie cookie = new HttpCookie("mycookie", "abc");
cookie.HttpOnly = true; //Seems to only affect script access
cookie.Secure = true; //Seems to affect only https transport
What property or method call am I missing to achieve an in memory cookie?
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"
[Code]....
I know how to write/create cookies in JavaScript.
//Create the cookies
document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work:
var cookieName = ReadCookie("Name");
document.getElementById('txtName').value = cookieName;
Edit with Answer:
I used this code.
<script type="text/javascript">
function getCookie(c_name)
{
if (document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name + "=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1;
c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1) c_end=document.cookie.length;
return unescape(document.cookie.substring(c_start,c_end));
}
}
return "";
}
function checkCookie()
{
Name = getCookie('Name');
Surname = getCookie('Surname');
Email = getCookie('Email');
Company = getCookie('Company');
Title = getCookie('Title');
if (Email!=null && Email!="")
{
//Populate the text boxes.
document.FormName.txtName.value = Name;
document.FormName.txtSurname.value = Surname;
document.FormName.txtEmail.value = Email;
document.FormName.txtCompany.value = Company;
document.FormName.txtjob.value = Title;
}
}
</script>
And called the checkCookie() function like so from the window.onload
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaScript'><!-- //
window.onload = initPage;
function initPage()
{
checkCookie();
}
//-->
I 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.
I would like to set the Login which will log auto when he return to site, if the user hasent logged off the site.and if he enter the site again he'll be logged in already.

View 1 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 5 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.
Is there a way to set a persistent session that would not expire when closing/re-opening a browser. The cookie that is used to store the session_id expires when the browser is closed.
I know we can make the Auth persistent (stay logged in when we close and re-open a browser). In this case, the cookie does NOT expire when the browser is closed
I have currently have a web application that caches a large amount of data (several hundred thousand entries) in memory for quick lookup and then in SQL Server as a persistent cache. Basically the information consists of geocodes of addresses where the geocode is retrieved via a remote web service which takes time if needed to be called continuously rather than cached.
Would using RavenDB (or other suggestions) be a better way of caching this information in a persistent store in terms of both speed and memory?
i have a list of fields that i would store for all the user session. I thought to create a class, insert the information in it and store the class in the session but i'm not sure this is the best way to do it (performances, etc). I should have a list of these informations that i can display in views, i can delete and i can update. How could i do this?
View 10 RepliesI'm building a page in asp.net that will use tiny mce to provide a rich text editor on the page. Tiny mce outputs the rich text as html which I would like to save to a database. Then at a later date, I want to pull the HTML from the database and display it in a page.
I'm concerned about allowing malicious html, js tags into my database that would later be output.
I should html encode/decode etc. to prevent a persistent xss attack and or sql injection attack?
I need to connect to a WebService provided by someone else. This WS (all https) has three methods that are accessible without having logged on:
login, logoff, getVersion . All other methods require that the login-method has been called before. Nothing special unto this point. However, the docs state that I have to make sure that (quote):
"All method calls between login and logoff are to be carried out by means of the same persistent http-connection (key word: http persistent connections or http connection reuse"
I seem to be unable to figure out how that would work - all WS'es I ever utilized were either taking user/pwd combinations in each method call or the login-method returned something like a SessionID which was then used for each subsequent call to a given method (i.e. passed as a parameter). If I call the login-method and subsequently call any method that requires authentication, the call will fail with an exception telling me that I need to log in first.
I have developed an asp.net application that I developed using visual studio express 2008.
With this application, I have 20 sales items. I can sell 10 of each item each day. Customers can order the items in advance but once an item has more than 10 orders for the day then I can not sell any more of the items for that given day. If a customer tries to order another item after 10 has already been ordered then I must tell them that no further items of that kind are available. So for each day there can be possible 200 orders total (20 items x 10 sales). Customers can order months in advance...
So, my question is what kind of storage device do I use to keep track of this kind of data? Database or application variable or other?
Iam building a website and i need to store somehow some informations that i will use in the whole site depending of the user type logged in.
Example:
1) User XPTO logs in
2) Query DataBase to see where he belongs
3) Store those 2 or 3 fields that i will get in Database in a persistent way to use it in the whole site.
Whats the best practices to do this?
When a user logs in into my website I have a custom membership provider that overrides ValidateUser and verifies that the user has sufficient rights etc.
However, when implementing a 'remember me' function through the default forms authentication using RememberMeSet, I also want to validate a user on the first request.
Is there some hook I can attach to that triggers when a user logs in with their persistent cookie?

View 1 Repliesi have a custom membership provider and do manual validation of the user when they log in and set a persistent cookie with this bit of code:
FormsAuthentication.RedirectFromLoginPage(this.txtEmail.Text,
this.cbRememberMe.Checked);
The cookie gets set fine. I can tell it has all the data it needs by looking at it in Fiddler once im validated. However coming back to the site im always getting prompted to log in again. I am starting to think the problem isn't how im saving the cookie but that maybe my custom membership isn't acutally looking for this auth cookie again. Or im naming it wrong or something.
Two things
1) My membership provider is custom and NOT added to web.config - it's a .cs file that connects to a CMS back end for the validation and it works fine logging people in and such it just never keeps (or uses) the persistent cookie.
NOTE: the persistence doesn't work anywhere (on my local machine / staging server or live server - Application name is simply "/")
NOTE 2: as an aside we have a google search applicance. Which we baked a 10 year cookie for on this site - we opened up the cookie and used the encrypted string in the google search appliance (this is how you get it to get past logins, etc) and this thing works great- it logs itself in no problem all the time. SO i am a bit lost as to why a user with an almost identical cookie is not getting logged in.
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()?
View 1 RepliesI am familiar with creating and persisting dynamic controls on the first load of a page and on subsequent postbacks but I am having trouble with the following user initiated scenario...
In my demo I have a placeholder, two buttons and a literal
[code]....
I'm creating a page that allows the user to create a new object that will later be stored in the database. The problem is that the design of ASP.NET data controls seems to insist upon only working with pre-existing data that has been stored in a database (or XML, etc...).
I'm basically trying to get the user to compose a list of items and specify a quantity for each item. I could do this by generating table rows but the rows are lost at each postback. The data view controls seem to be designed only to be bound to a data source but until the list is complete, the data can only be in memory.
What control is appropriate for this and how can I achieve this with that control?
