IE的缓存导致ajax不走后台的问题

var error = false;
$(document).ready(function(){
$('#pagination').bootpag(
{
total : Math.ceil('${page ne null ? page.context.pageCount : 1}'/1),
page : Math.ceil('${cpage ne null ? cpage : 1}'/1),
maxVisible : 10,
leaps: true
}).on('page', function(event, num) {
$.ajax({
type : "GET",
url : "<%=basePath%>/admin/listUser?random=" + new Date().getTime(),
data :  {pageNum: num, numPerPage: 10, name: $("#name").val()},
success : function(data) {
var win = parent.frames[1].frameElement.contentWindow;
win.document.contentEditable = true;
win.document.clear();
win.document.open();
win.document.write(data);
win.document.close();
}

});

});

});

<pre name="code" class="javascript"><%
response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );
%>

The same effect can be achieved by using meta tags in the HTML header:

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Expires" content="Sat, 01 Dec 2001 00:00:00 GMT">
