Hi,
I am using JSP/Servlets to display my pages. One of the pages has a gif file
embedded thru' the img tag.
For every request the gif is regenerated by the servelet
The geneated html file has
<!--
<meta http-equiv="Expires" content="0">
<meta http-equiv="Pragma" content="No-cache">
<meta http-equiv="Cache-Control" content="No-cache">
-->
In spite of all this, only the gif is cahced by both Netscape and IE and
will show the latest gif file only when refreshed.
Any ideas?
Thanks,

>SCENARIO:
>1) User starts at Logon page, provide user name and password, then hit

>2) Main page reads data from form using getParameter and allows user in
>Main page if user valid.
>
>3) User clicks Back button and goes back to Logon page (the server

>4) Without the user providing proper user name and password, user clicks
