/**

|
* By default DataTables only uses the sAjaxSource variable at initialisation
|
|
* time, however it can be useful to re-read an Ajax source and have the table
|
|
* update. Typically you would need to use the `fnClearTable()` and
|
|
* `fnAddData()` functions, however this wraps it all up in a single function
|
|
* call.
|
|
*
|
|
* DataTables 1.10 provides the `dt-api ajax.url()` and `dt-api ajax.reload()`
|
|
* methods, built-in, to give the same functionality as this plug-in. As such
|
|
* this method is marked deprecated, but is available for use with legacy
|
|
* version of DataTables. Please use the new API if you are used DataTables 1.10
|
|
* or newer.

* @param {string} [sNewSource] URL to get the data from. If not give, the

* previously used URL is used.
|
|
* @param {function} [fnCallback] Callback that is executed when the table has
|
|
* redrawn with the new data
|
|
* @param {boolean} [bStandingRedraw=false] Standing redraw (don't changing the
