Refresh button on mobilewebform not giving latest version of page

[Chumley Walrus]

I am trying to get a Refresh button to work on a mobilewebform that has
live sports scores. The code behind (C#) for the refresh button is:

private void Page_Load(object sender, System.EventArgs e)
{
if (!Page.IsPostBack)
PopulateDateList();
Response.Redirect("selfPage");
}
...and in the html header for the aspx page, I am using some cache tags:
<meta Http-Equiv="Cache-Control" Content="no-cache">
<meta Http-Equiv="Pragma" Content="no-cache">
<meta Http-Equiv="Expires" Content="0">

....but I still get no new version of the page when I hit the refresh
button.

??
