Use additional flag to indicate that the the actual downloading should be made. In a meantime you can show a "Please wait" message. Like this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="3; url=<%=HttpUtility.HtmlAttributeEncode(Request.Url.OriginalString + &IsDownloading=true")%>">
</head>
<body>
<h2>Your download will start shortly...</h2>
</body>
</html>
Code-behind:
protected void Page_Load(object sender, EventArgs e)
{
if(string.Compare((Request.QueryString["IsDownloading"] ?? string.Empty).Split(new char[] { ',' }).First(), "true", StringComparison.InvariantCultureIgnoreCase) == 0)
{
// Make a file transfer
}
}
