you can transfer you asp session to asp.net session. here i give small demo for that.

steps:

1) create asp page (mypage.asp)

   1:
   2: <%@LANGUAGE="Vbscript" CODEPAGE="1252"%>
   3: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
   4: <html xmlns="http://www.w3.org/1999/xhtml">
   5: <head>
   6: <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
   7: <title>Untitled Document</title>
   8: </head>
   9: <form name='form1' action='login.asp' method='post'>
  10: User Name : <input type='text' name='username'>
  11: <br>
  12: <input type='submit' value="Login">
  13: </form>
  14: <body>
  15: </body>
  16: </html>

2) create second asp page (login.asp)

   1: <%

   1:


   2: If Request.Form("username") = "" then


   3:     Response.Write("Login Failed.<br><br>")


   4: else


   5:      Response.Write("Transfer Session in To Hidden Field")


   6:     ' create asp session user here


   7:      Session("user") =Request.Form("username")


   8:      ' in the form action go to the aspx page called default.aspx


   9:      Response.Write("<form name='form1' id='form1' action='Default.aspx' method='post' >")


  10:


  11:      For each Item in Session.Contents


  12:         Response.Write("<input type=hidden name=" & Item)


  13:         Response.Write( " value=" & Session.Contents(item) & " >")


  14:      next


  15:      Response.Write("</FORM>")


  16:


  17:      Response.Write("<script>form1.submit();</script>")


  18: End If


%>

3) create aspx page with (asp.net with c#)

   1: <%@ Page Language="C#" %>
   2:
   3: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
   4:
   5: <script runat="server">

   1:


   2:     protected void Button1_Click(object sender, EventArgs e)


   3:     {


   4:         //redirect to asp page


   5:         Response.Redirect("myasp.asp");


   6:     }


   7:     protected void Page_Load(object sender, EventArgs e)


   8:     {


   9:         //get the Request 


  10:         for (int i = 0; i < Request.Form.Count; i++)


  11:         {


  12:             //transfer value


  13:             Session[Request.Form.GetKey(i)] = Request.Form[i].ToString();


  14:         }


  15:         //check the session


  16:         if (Session["user"] != null)


  17:         {


  18:             Response.Write("Hi " + Session["user"].ToString());


  19:         }


  20:     }


</script>
   6:
   7: <html xmlns="http://www.w3.org/1999/xhtml" >
   8: <head runat="server">
   9:     <title>ASPX Page</title>
  10: </head>
  11: <body>
  12:     <form id="form1" runat="server">
  13:     <div>
  14:         <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>
  15:     </form>
  16: </body>
  17: </html>

4) now start the application start page is (mypage.asp).

click on the login button it will go to login.asp page.

in the login.asp page session is create Session(“user”) =Request.Form(“username”)

if login is success then page is go to the default.asp.

on the default.aspx page load event

//get the Request

for (int i = 0; i < Request.Form.Count; i++)

{

//transfer value

Session[Request.Form.GetKey(i)] = Request.Form[i].ToString();

}
