title: getXMLHTTP() issue
body: <p>I have the following code:</p>
  
  <pre><code>&lt;script type="text/javascript" language="javascript"&gt;
  &lt;!--
  function getXMLHTTP() { //function to return the xml http object
          var xmlhttp=false;    
          try{
              xmlhttp=new XMLHttpRequest();
          }
          catch(e)    {        
              try{            
                  xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
              }
              catch(e){
                  try{
                  req = new ActiveXObject("Msxml2.XMLHTTP");
                  }
                  catch(e1){
                      xmlhttp=false;
                  }
              }
          }
  
          return xmlhttp;
      }
  
      function wait1()
      {
          document.getElementById('comment').innerHTML="Please wait...";    
      }
  
      function getComment(strURL) {        
  
          var req = getXMLHTTP();
  
          if (req) {
  
              req.onreadystatechange = function() {
                  if (req.readyState == 4) {
                      // only if "OK"
                      if (req.status == 200) {                        
                          document.getElementById('comment').innerHTML=req.responseText;                        
                      } else {
                          alert("There was a problem while using XMLHTTP:\n" + req.statusText);
                      }
                  }                
              }            
              req.open("GET", "comment_form.php", true);
              req.send(null);
          }
  
      }
  //--&gt;
  &lt;/script&gt;
  
      &lt;div id="comment"&gt;
  &lt;form  action="javascript:get(document.getElementById('comment'));wait1()" method="post" enctype="multipart/form-data" &gt;
  &lt;input type="submit" name="Submit" value="Post Your Comment" /&gt;
  &lt;/form&gt;
  &lt;/div&gt;

  <p>I am sure I used the same in past running smoothly, but now it doesn't seem to be working. I think something is messed up there, but not able to figure out.</p>
  
  <p>I would be thankful if I get the solution.</p>
