Server side Ajax Post is executing repeatedly

thomaska

Hi,
I have a datatable getting data from a server side webapi. I found that as soon as the page is loaded and the datatabe is loaded then execute the ajax post method repeatedly probably every 1 second or two. Any suggestions why is this happening, because this is considered as DDOS atack to webapi firewall.

Following is the ajax configuration:

var dt_users = dt_users_table.DataTable({
ajax: {
global: false,
cache: false,
url: '/Dashboard/Administration/Users/FetchUsers',
type: 'POST',
datatype: 'json',
headers: {
'X-CSRF-TOKEN': $('#__ejRequestVerificationToken').val()
}
},
processing: true,
serverSide: true,
paging: true,
pageLength: 10,
searching: true,
responsive: true,
ordering: true,
order: [[1, "asc"]],
columns: [
{ data: 'id' },
{ data: 'id' },
{ data: 'fullName' },
{ data: 'userName' },
{ data: 'status' },
{ data: 'partnerType' },
{ data: 'phoneNumber' },
{ data: 'twoFactorEnabled' },
{ data: 'dateOfBirth' },
{ data: 'lastLogin' },
{ data: 'action' }
]

There is nothing in your code snippet that would cause Datatables to send multiple ajax requests. Possibly you have something calling draw() or ajax.reload() somewhere. Please post a link to your page or test case replicating the issue so we can help debug.

"datatables.net-fixedcolumns-bs5": "4.3.1",
"datatables.net-fixedheader-bs5": "3.4.1",
"datatables.net-responsive": "2.5.1",
"datatables.net-responsive-bs5": "2.5.1",
"datatables.net-rowgroup-bs5": "1.4.1",
"datatables.net-select-bs5": "1.7.1",

to
"datatables.net": "2.1.8",
"datatables.net-bs5": "2.1.8",
"datatables.net-buttons": "3.1.2",
"datatables.net-buttons-bs5": "3.1.2",
"datatables.net-fixedcolumns": "5.0.3",
"datatables.net-fixedcolumns-bs5": "5.0.3",
"datatables.net-fixedheader": "4.0.1",
"datatables.net-fixedheader-bs5": "4.0.1",
"datatables.net-responsive": "3.0.3",
"datatables.net-responsive-bs5": "3.0.3",
"datatables.net-rowgroup": "1.5.0",
"datatables.net-rowgroup-bs5": "1.5.0",
"datatables.net-select": "2.1.0",
