title: IE8 loads images and css from server and does not save them in cache, how to force IE takes images from the cache?
body: <p>I created web site, JSP, runs on Tomcat.</p>
  
  <p>IE8 does not load images from cache, although I try that and it loaded from cache in mozilla.
  Cache is not disabled in my IE8.</p>
  
  <p>Tomcat log for mozilla produces 304 status code:
  "GET /petelina/images/main/logo.png HTTP/1.1" 304 -</p>
  
  <p>Tomcat log for IE8 is always 200:
  super [26/Nov/2010:20:10:07 +0200] "GET /petelina/images/main/bg_left_column.gif HTTP/1.1" 200 1394</p>
  
  <p>res.setDateHeader("Expires", System.currentTimeMillis() + 604800000L); - does not help, if I set it in filter for static content.</p>
  
  <p>How to force IE8 work with cache?????!!!!</p>
