Cookie value lost when redirect to a new page. (iOS only) RRS feed

    Hi guys, my web application having an issue.

    Cookies value will be lost when redirecting to a new page (dashboard.aspx)

    This problem ONLY occurred when I log-in using apple phone (iOS). Working fine in android phone and desktop.

    I have confirmed my safari is Cookies Enabled. Any idea?


    If IsNothing(Request.Cookies("CustomerInCakes")) = False Then
       Response.Redirect("/customer-portal/dashboard.aspx", False)
       me.lbl_result.Text = "Cookies is NOT existing"
    End If


            If IsNothing(Request.Cookies("CustomerInCakes")) = True Then
                Response.Write("Cookies is NOT existing")
                Response.Write("Cookies is existing")
            End If
            Dim colCookies As ArrayList = New ArrayList
            Dim i As Integer = 0
            Do While (i < Request.Cookies.Count)
                i = (i + 1)
            Me.GridView.DataSource = colCookies


      <browser refID="Default">
          <adapter controlType="System.Web.UI.HtmlControls.HtmlForm" adapterType="FormRewriterControlAdapter" />
          <capability name="cookies" value="true" />

    I've seen this asked quite few times in this forum and never remember to test about this. My understanding is that when sending both cookies and doing a redirect some browsers (ie Safari ?) are doing only the redirect. Most often the response is to redirect on the client side instead.

    Edit: old but for example: https://discussions.apple.com/thread/7770177

    (you have a single redirect or in close succession, this is not cross domain, you may want just to try a basic test to make sure what happens).

And yes it's NOT cross domain redirection.

    Based on my testing.. my cookies is existing before redirecting to page B. Any idea?

    It was just to point it seems a Safari behavior.

    The usual suggestion  is to render the page so that cookies are taken into account and include javascript code such as document.location.href="somewhere"; so that cookies are set and redirection is done.

    I would test maybe with Chrome or Edge on the same iOS version (wonder if this is Safari or some underlying behavior in the http stack). This is which version of Safari/iOS ?

    I have tried using javascript to do redirection instead of response.redirect but still not working. (cookies is lost)

    ScriptManager.RegisterStartupScript(Me.Page, Page.GetType, "text", "Redirect()", True)

    my iOS version is 12.1.2 

    I have tried with (Firefox version 14.0) but still failed.

    You are 100% sure you removed the server side redirection ?

    Else I would try maybe one page that set cookies and on which I click manually to go another page. If cookies are not sent yet, it would really point at a general cookie issue (try maybe to clear the browser cache to see what happens) rather than just this "set cookie and redirect in the same response" issue.

    Or maybe you mistakenly use http with "secure cookies" (they are sent back only if using https).

    There is no indication that you have set a cookie in the first place.  Can you share the code that sets the cookie and explain the design?  Try setting a break point on the code that creates the cookie and verify it works.
