I'm totally unclear why you're using JavaScript to open another page
in the same window, but as far as your immediate question -- you can
have `ServletAcces` return no-cache headers and/or append a unique
(timestamp) string to the URL to minimize browser caching.

Here's one approach to the latter:

<script type="text/javascript">
function init()
{
    var t = document.getElementById("s");
    t.search = t.search + "&date=" + Date.parse(new Date());
}

window.onload=init;
</script>

<a id="s"
    href="ServletAcces?nomBase=etudiant"
    onclick="window.open(this.href,'_self','status=yes');"
    >
<img src="bouton.gif"/></a>


(I put the onclick in there, though it's superfluous; the normal
link will open in the same window, unless you change the '_self'
to something else...)

HTH!
