do you have viewstate enable? where do you assign session and variables?

I can't see an reason why you'd have any issues. By variables, do you mean GET or POST data?
How are you settings the session data?

The following code keeps the Session values & Querystring as expected (in IE6 & Firefox3)

<%@ Page Language="C#" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<script runat="server">
 
  protected void Page_Load(object sender, EventArgs e) {
    if (Session["foo"] == null) {
      Session["foo"] = DateTime.Now;
    }
 
    HtmlMeta meta = new HtmlMeta();
    meta.HttpEquiv = "REFRESH";
    meta.Content = "5";
    Page.Header.Controls.Add(meta);
 
    QueryString.Text = Request.QueryString.ToString();
    FooSession.Text = Session["foo"].ToString();
 
  }
</script>
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
  Querystring: <asp:Label ID="QueryString" runat="server"></asp:Label><br />
  Session["foo"]: <asp:Label ID="FooSession" runat="server"></asp:Label>
</body>
</html>

Yes I tried, but it doesn't work. Because the refresh function is a clean up function too.
I tried to use java script function but it doesn't work because I've web services and user controls.

In this code:
meta.HttpEquiv = "REFRESH";
meta.Content = "15";
Page.Header.Controls.Add(meta);

I need to retrieve some variables/values/session but I dont know to do it.

Thank you

you can assign values in Page_Init event and can see whether it makes any difference to you as it should work even without changing anything but you can try INIT event

I don't know why is the problem with my session values.
When I call the page, I execute default.aspx, with a masterpage, inside the default.aspx I've a user control with a drop down list and I get the value from there.
Then I've the auto refresh page in that moment is when I lost the session/variables values.

Here's the code I using

    protected void Page_Load(object sender, EventArgs e)
    {
 
 
        if (Session["HourSelected"] == null)
        {
            Session["HourSelected"] = Convert.ToDouble(Search1.HourValue);
            Response.Write(Session["HourSelected"]);
        }
 
        HtmlMeta meta = new HtmlMeta();
        meta.HttpEquiv = "REFRESH";
        meta.Content = "5";
        Page.Header.Controls.Add(meta);
 
 
        Session["HourSelected"] = Convert.ToDouble(Search1.HourValue);
 
        timeIni = DateTime.Now.AddHours(Convert.ToDouble(Session["HourSelected"]));
        timeFin = DateTime.Now;
        GV_Servers.DataBind();
 
 
 
    }
