I created an asp.net mvc4 application and depolyed it successfully in server.

When I login into the deployed web application its working fine, but when different user login from different device with their own credential,by surprise my page is visible to them. They cant access their profile instead of that my profile details are displaying to them.

Once after I logged out they can view their pages and its happening vice versa.

I am dumping my head to figure out the problem. I pasted the controller and view code below.

Controller.cs

[HttpPost]
        public ActionResult LogIn(ECusertables user,int id=0)
        {
            
                if (IsValid(user.Email, user.Password))
                {
                    user = db.ECusertables.Where(u => u.Email == user.Email).Select(i => i).FirstOrDefault();
FormsAuthentication.SetAuthCookie(user.Email, false);
}
}

View.Cshtml

 @if (Request.IsAuthenticated)
        {
            <div align="right" style="margin-removed10px;">  @Html.Encode(User.Identity.Name) 
            </div>
        }



Thanks in adavnce.
