title: App Engine NO CACHE JSP
body: <p>I want to disable the cache for a JSP file on my google app engine website.</p>
  
  <p>I have this:</p>
  
  <pre><code>&lt;%
          // Set to expire far in the past.
          response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT");
  
          // Set standard HTTP/1.1 no-cache headers.
          response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");
  
          // Set IE extended HTTP/1.1 no-cache headers (use addHeader).
          response.addHeader("Cache-Control", "post-check=0, pre-check=0");
  
          // Set standard HTTP/1.0 no-cache header.
          response.setHeader("Pragma", "no-cache");
  %&gt; 
  </code></pre>
  
  <p>But the JSP is still in cache. I need to kill the user session and login again in order to reload the JSP code.</p>
  
  <p>How do I disable the cache for a app engine JSP?</p>
