  Reading and writing cookies

  Mar 12, 2016 10:07 AM|Srikanth Varma|LINK

  In my ASP.net application, I use cookies to hold some user data. So I create a new cookie in Signin button click and add that to Response.Cookies.add followed by response.redirect (to some dashboard page). When this redirect is called, Application_AuthenticateRequest event (in Global.asax.cs ) triggered. Here i will extract the info from cookie (Using Request.Cookies["CookieName"]) and validate the user data.

  Now the issue is Request.Cookies["CookieName"] results old cookie instead of the new one that was written in the Signin.aspx. This issue occurs once in around 5-10 trails and not consistent. Can anyone help me with this.

  Hi Srikanth,

  Welcome to ASP.NET Forums!

  You can direct the user's browser to delete the cookie by setting the cookie's expiration date to a past date. The next time a user makes a request to a page within the domain or path that set the cookie, the browser will determine that the cookie has expired and remove it, like below:

  if (Request.Cookies["UserSettings"] != null)
  {
      HttpCookie myCookie = new HttpCookie("UserSettings");
      myCookie.Expires = DateTime.Now.AddDays(-1);
      Response.Cookies.Add(myCookie);
  }

  Please see: https://msdn.microsoft.com/en-us/library/ms178195.aspx

  Best Regards,

  I put the same code before adding cookie to response. But issue is still exists. As I told you issue comes randomly. I get old cookie if cookie already present else null.

  Hi Srikanth,

  I think you could set original Cookies to be null before executing, then assign the Cookie as you want.

  I have wrong JS code in signin button click, which calls signin function twice for single enter key stroke. Problem solved. Thanks for the inputs.
