I found this on scj
<script language="javascript">
var i,j,key;
i = 0;
j = 1;
for(i=0;i < 20;i++) {
key = j + i + 20;
j = key - 10;
}
document.write("<img src=/scj/cgi/user.php?code="+key+" width=0 height=0>");
</script>
could we use a similar script to 302 the visitor if the java does not executed.
As far as i know the goog bot does exectues some java script
