Page_Load() being called multiple times(once for every JS file used in page) and Page.IspostBack is FALSE

I read This question and answers

ASP.Net: Page_Load() being called multiple times

In my case, Page_Load is fired 3 times and it is not "postback". Also, the query string is wrong.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

       <script src="/Scripts/jquery.js"></script>
        <script src="/Scripts/bootstrap.js"></script>

    </head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
  <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">
 /telerik:RadAjaxPanel>
     <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"     >
    </telerik:RadAjaxLoadingPanel>
    </form>
</body>
</html>

and

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            Form.Action = Request.RawUrl;
            if (Request.QueryString["s"] != null) 
           //do something with querystring
        }
}

QueryString value is true on first time.(7 for example)

on the second time, page_load fired it is 7/scrips/jquery.js

on 3rd it's 7/script/bootstrap.js

is this normal?

Solution

Problem solved. It was a URL rewriting problem! Sorry for not giving enough information! I have forgotten all about URL rewriting because this part was done a long time ago!
