I don't know anything about JSP or Apache.  But you folks do!  So...

If you go to this page:
     http://www.google.com/
and then look at the IE6 cache files, you will see that the "Expiration Date" for the file named
      http://www.google.com/images/logo.gif
is set some time in the year 2038

But if you look at the cached GIF files that come in from this page
     https://www.experts-exchange.com
for instance,
      https://www.experts-exchange.com/images/logoBottom.gif
there is no expiration date.  

1) Why is that?
2) How can a site that uses JSP serve up a GIF file and specify an expiration date for it?
