[개발] AJAX - Rolling List

요번 프로젝트때 만든 롤링리스트...
10초마다 ajax함수를 호출해서...
함수에 요청하는 건데.. 부하가 많이 걸려서 OTL

[aspx]

<UL id=RollListSubList>
<asp:Literal id=ltrMainRssList EnableViewState="False" Runat="server"></asp:Literal>
</UL>
<script language="javascript" type="text/javascript">
   function ReloadRollList(){Ajax.PG.ucRollListNetSub.reloadList(Reload_CallBack);}
   function Reload_CallBack(res){
        if(res != null){
              var divRss = document.getElementById('RollListSubList'); divRss.innerHTML = res.value;}}
   setInterval("ReloadRollList();", 10000);
</script>

[cs]

[AjaxPro.AjaxMethod]

  {
   int temp = 0;
   DataSet ds = RollListNetBiz.GetListAdminRecommand(1,30, out temp);

     string Title = dt.Rows[i]["Title"].ToString();
     string Content = dt.Rows[i]["Content"].ToString();

     string MasterName = dt.Rows[i]["MasterName"].ToString();

     Title = Utility.RemoveHTML(Title);
     Title = Utility.RemoveHTMLTag(Title);
