I am new to asp classic and trying to call asp classic function from jquery ajax but it is giving 404 error. I want to return records in json in this javascript code.

My javascript code is

$.ajax({
 type: "POST",
 url: "../dbFile.asp",

 data: {"Id"="10"},
 error: function(XMLHttpRequest, textStatus, errorThrown){
     alert(textStatus);
 },
 success: function(result){
    alert("success");
 }
});
 return false;
});

and my vb script function in asp classic file is

Function GetAllRecords()
   dim cmd, rs

   set cmd=Server.CreateObject("ADODB.Command")

   cmd.ActiveConnection = conn

   cmd.CommandType = 4

   cmd.CommandText = "GetAllRecords"

   set rs=Server.CreateObject("ADODB.Recordset")

   set rs=cmd.Execute()

   set GetAllRecords= rs

   set rs=nothing

   set cmd=nothing

End Function

Please guide i am stuck here.
