How Many Ways To Open Multiple Windows With A Click?

Are there other ways to open multile windows at once?

<SCRIPT language="JavaScript">
function open1() {
var open1 =
window.open('http://google.com/CheckEnviro.pl','','scrollbars=yes,height=600
,width=800,resizable=yes');
}
function open2() {
var open2 =
window.open('http://google.com/CheckEnviro.pl','','scrollbars=yes,height=600
,width=800,resizable=yes');
}
function open3() {
var open3 =
window.open('http://google.com/CheckEnviro.pl','','scrollbars=yes,height=600
,width=800,resizable=yes');
}
// -->
</SCRIPT>

<A href="javascript:open1();open2();open3();">Click Here to open all</A>

Here is what I have now, but I need something which can pass HTTP_REFEREER.
The window.open does not do that.
