Web Security in IE VS Chrome & Firefox (bug)

Why is the Web Security is working differently on different browser:


I have two applications

One is a simple HTML application and another one is an ASP.NET MVC4 WebApi application and the projects are inside of same solution and i have set multiple start-up project for run the application for same time .

Working version:

I have Used Web Security in the Web API project. I did full implementation of web security...

Login Action Code

// GET api/company
public HttpResponseMessage Login(LoginRequest loginRequest)
        if (WebSecurity.Login(loginRequest.EmailAddress, loginRequest.Password, true))
            var userDetails = new string[2];
            userDetails[0] = loginRequest.EmailAddress;
            var currentUSerRole = Roles.GetRolesForUser(loginRequest.EmailAddress);
            userDetails[1] = currentUSerRole[0].ToString();
            HttpResponseMessage response =
                Request.CreateResponse(HttpStatusCode.Accepted, userDetails);
            return response;
            HttpResponseMessage response
                = Request.CreateResponse(HttpStatusCode.Unauthorized);
            return response;
    catch (Exception e)
            HttpResponseMessage response
            = Request.CreateResponse(HttpStatusCode.Unauthorized);
           return response;

*WebSecurity.Login* is working on all browsers when i call the login method using Ajax. But I have another method in another controller, That named as CurrentDateAndUser


public HttpResponseMessage CurrentDateAndUser()
    if (WebSecurity.IsAuthenticated)
        int userId = WebSecurity.CurrentUserId;
        string[] currentDateAndUSerId = new string[2];
        currentDateAndUSerId[0] = userId.ToString();
        currentDateAndUSerId[1] = DateTime.UtcNow.ToString();

        HttpResponseMessage response =
            Request.CreateResponse(HttpStatusCode.Accepted, currentDateAndUSerId);
        return response;
    HttpResponseMessage responseNew =
    return responseNew;


  • If I call the CurrentDateAndUser method from Microsoft Internet Explorer Using an Ajax call, then everything works. The WebSecurity.IsAuthenticated returns true and is working well.


  • If I call the CurrentDateAndUser method from Google Chrome Or Mozilla Firefox using an Ajax call, then nothing works. The WebSecurity.IsAuthenticated always returns false.

I don't know why. If you have any idea, then please let me know.

I also found a similar problem (not sure if it is a real issue):

When I run my application with Fiddler, I see a different result:

When i call the CurrentDateAndUser method from IE, the request is:

enter image description here

I can see the Cooke/Login values in above image

But When i call the CurrentDateAndUser method from Chrome And Firefox , the request is:

enter image description here

I can't see the cookie values, meaning that the Web Security.IsAuthenticated property is returning false.

Is it Bug in WebSecurity?????


My Ajax request code is

function GetCurrentUserId() { 
    return $.ajax({
        method: 'GET',
        url: rootUrl + '/api/Common/CurrentDateAndUser',
        async: false
    }).success(function (response) {
        return response[0];

    }).error(function () {
        toastr.error('Somthing is wrong', 'Error');

This request does not send the Auth Cookie values to Web API method when I run the application in Chrome and Firefox, however, this request sends the cookie values to the API method, if it is run in IE

i have posted the Image , Please take a look at the above image



The issue is not with web security at all, it's with the way you implement your security. You should never be using a userid, email, or anything important in the cookies.

I would suggest you use the FormsAuthentication class to encrypt and decrypt your cookies, and even so, only store something such as the SessionID plus a custom hash of that session ID to verify your self when you decrypt the cookie

Here is a site that gives a pretty good example: http://www.c-sharpcorner.com/uploadfile/nipuntomar/update-formsauthenticationticket/


There are 3 things around it:

WebSecurity.IsAuthenticated actually returns the value of HttpRequest.IsAuthenticated, which is true if the Forms Authentication cookie has been set and is current. It's not available until the user makes the next request after successfully logging in, which is why you are seeing the behaviour that you describe.

I remember reading on MSDN or someplace, the WebSecurity.IsAuthenticated does not work until the page is fully loaded. Meaning if you login a user in a page and in the same flow of code you check IsAuthenticated, it will NOT return True. For IsAuthenticated to be True the page has to be reloaded or use the better practice; which is to redirect the user to another secured page as soon as the login is successful and in that page check IsAuthenticated.

We had the same issue with Chrome (version 21.0.1180). Despite that we see expiration date on Header, some Chrome in Windows XP ignored it. Then we removed the Expiration Date and Chrome accepted keep the session cookie without problems.

So what to do is: After login try to check this on new page not on same page.

Also try to set cookie explicitly

System.Web.Security.FormsAuthentication.SetAuthCookie(user.Username, false);

I don't know if this will help or not.

But I remember I was learning jQuery ajax So I setup a simple project on my laptop. When I tested it, it worked fine on IE, but failed in Chrome. After searching for hours, I found that Chrome will not allow AJAX requests from the local machine. When I tested it using an actual web server it worked fine for IE and Chrome.

So my question and advice is: are you testing on the same machine? Try to deploy it to a machine running a web server with a unique domain name and test your application!
