Can any one help me, I would like to Modify the XML request made for UPS Real Time Shipping.

where can i find it to edit.

i see that in checkoutshipping.aspx.cs
C#/VB.NET Code:
 using (SqlConnection con = new SqlConnection(DB.GetDBConn()))
                {
                    con.Open();
                    using (IDataReader rs = DB.GetRS("Select RTShipRequest,RTShipResponse from customer  with (NOLOCK)  where CustomerID=" + ThisCustomer.CustomerID.ToString(), con))
                    {
                        if (rs.Read())
                        {
                            String s = DB.RSField(rs, "RTShipRequest");
                            s = s.Replace("<?xml version=\"1.0\"?>", "");
                            try
                            {
                                s = XmlCommon.PrettyPrintXml("<roottag_justaddedfordisplayonthispage>" + s + "</roottag_justaddedfordisplayonthispage>");
                            }
                            catch
                            {
                                s = DB.RSField(rs, "RTShipRequest");
                            }
                            tmpS.Append("<b>" + AppLogic.GetString("shoppingcart.aspx.5", SkinID, ThisCustomer.LocaleSetting) + "</b><br/><textarea rows=60 style=\"width: 100%\">" + s + "</textarea><br/><br/>");

                            s = DB.RSField(rs, "RTShipResponse");
                            try
                            {
                                s = XmlCommon.PrettyPrintXml("<roottag_justaddedfordisplayonthispage>" + s + "</roottag_justaddedfordisplayonthispage>");
                            }
                            catch
                            {
                                s = DB.RSField(rs, "RTShipResponse");
                            }
                            tmpS.Append("<b>" + AppLogic.GetString("shoppingcart.aspx.6", SkinID, ThisCustomer.LocaleSetting) + "</b><br/><textarea rows=60 style=\"width: 100%\">" + s + "</textarea><br/><br/>");
                        }
                    }
                }

                DebugInfo.Text = tmpS.ToString();
            }
        }
