var url에 결과물은 뭔가요?

도통 자바는 모르는터라

<script language="javascript">
      function f_onmouseover(strTargetID,iconNo)
     {

      var strTargetID = strTargetID;
      var url = "./infor.asp?strTargetID=" + escape(strTargetID)+"&iconNo="+escape(iconNo);
     //alert(url)
      AjaxReques.open("post", url, true);
      AjaxReques.onreadystatechange = getgosioninfoview;
      AjaxReques.send(null);
      var bb="<table  border='0' cellspacing='0' cellpadding='0' ><tr><td><div id='ajax_div_insert1'>  로딩중...</div></td></tr></table>"
     return  bb ;
       }
      function getgosioninfoview()
      { 
 
     if (AjaxReques.readyState == 4)
     {
        if (AjaxReques.status == 200)
       {      
        var response = AjaxReques.responseText;      
        document.getElementById("ajax_div_insert1").innerHTML =response;
        }
       else alert("status is " + AjaxReques.status);
      }
 
       }
