I am new to this and I am using server side processing with ajax to an asp page. When I define more than 8 columns for my table I get an ajax 404 error but it works fine with 9 or less columns. I have posted my code below. You will notice some of it commented out in the table and asp array so that they match up. If I uncomment one more th and one more array then I get the 404 ajax error.

Here is the javascript

$(document).ready(function() { var table = $('#tbl_call_log').DataTable({ "serverSide": true, "ajax": "get_call_data.asp", "searching": false, "deferRender": false }); } );

Here is the asp page code:

Dim objWSHNetwork
Dim SQLserver, SQLconnect, query, recordset
Dim sEcho, iDisplayLength, iDisplayStart, sSearch, iTotal, sql, conn, rs, rs1, a, GetRecords_cmd, Records, arrRecords
Dim iTotalDisplayRecords, strWhere, strOrderBy, order

Set a = jsArray()

'sSearch = Request("sSearch")

'SEARCH - here we make the Where clause that will be used in the SQL query. You only put here the fields you want to search
' strWhere = " AND (engine LIKE '%" & sSearch & "%' OR "

' strWhere = strWhere & " platform LIKE '%" & sSearch & "%' OR "
' strWhere = strWhere & " version LIKE '%" & sSearch & "%' OR "
' strWhere = strWhere & " grade LIKE '%" & sSearch & "%')"

'ORDERING
'passes through all cols and first check if the column is sortable, if yes then construct
'the variable "order" that list in order the sequence of ordering
' for k=0 to 4
' if Request("bSortable_" & k)="true" then
' order = order & Request("iSortCol_" & k) & " " & Request("sSortDir_" & k)
' end if

' order = Replace(order,"1",", browser")
' order = Replace(order,"2",", platform")
' order = Replace(order,"3",", version")
' order = Replace(order,"4",", grade")

'here we eliminate the first comma of the variable "order"

' order = Right(order, Len(order)-1)

'here we create the variable "strOrderBy" that will be used in the SQL query
