title: disabling cache on jquery
body: <p>I am using jquery and jstree plugin to load some images when clicked on a jstree node. It looks like when I click a jstree node, it first checks the cache and if not in cache, noghting happens. I have to click the node again to load it from the server. (if the images in cache, first time click on the node works.)</p>
  
  <p>So, the behavior is not consistent for the end user. The first click on the jstree node, I should go to the server to retreive the image and put it in a div. I've been looking at this for awhile now, I couldn't come up with any solution.</p>
  
  <p>I am reaching out this community, maybe someone has seen this before and can help.</p>
  
  <pre><code>$(document).ready(function() {
      $("#div_tree").jstree({
          "xml_data": {
              "ajax": {
                  "url": "tree.xml"
              },
              "xsl": "nest"
          },
          "plugins": ["themes", "xml_data", "ui", "types"]
      }).bind("select_node.jstree", function(event, data) {
          var node_id = data.rslt.obj.attr("id");
          if (node_id = "tree_a") {
              $("#mydiv").html(myPic1);
          }
  </code></pre>
  
  <p>Is there a quick way to disable jquery cache, so that everytime I click on a jstree node, I should get the images from the server.</p>
