How to turn off the anti-cache feature in 1.7

Yun

Hi Allan,

Our team is using your datatables, it works great!
After I upgrade it to 1.7.3, I found in the requested AJAX url there follows "?_=random number",
I think this is the "anti-cache" feature released in 1.7.
However, I'm using the CodeIgniter framework in PHP, and the CodeIgniter forbids the GET arrays.
I can't get data correctly if the URL follows with "?_=xxx".

So, could you tell me how to turn off the anti-cache feature in 1.7.3?

Many thanks!

Yes indeed, what you need to do is make use of the fnServerData callback function: http://datatables.net/usage/callbacks#fnServerData . DataTables uses the following by default:

[code]
$.ajax( {
"url": url,
"data": data,
"success": callback,
"dataType": "json",
"cache": false,
"error": function (xhr, error, thrown) {
if ( error == "parsererror" ) {
alert( "DataTables warning: JSON data from server could not be parsed. "+
"This is caused by a JSON formatting error." );
}
}
} );
[/code]
That can be modified as needed.
