bStateSave not sending cookie.

Hi everyone.

I'm having a problem with the bStateSave property in DataTables 1.9.
The attribute is enable (true) but when i filter some data and go to another page, when i return the filter isn't there anymore.

$('.example').dataTable({
		"bPaginate": true,		
		"bRetrieve": true,
		"bDestroy": true,
		"bSortClasses": false,
		"bStateSave": true,
		"iCookieDuration": 3600,
		"sPaginationType": "full_numbers"
	});

Using Chrome, I verified the page information (right-click button) and the cookie wasn't set.

Need support, thank you all.
