Cache problem for servlet opening new browser window

Question

Requirement:
I have JSP page say summary.jsp with link "print account summary"
When user clicks on this link, new browser open with PDF document of summary.jsp
This new browser window should not have address bar and toolbar.
Solution:
Servlet called PrintSummary which sets contenttype=application/pdf and sends the data to outputstream.
href of link is
Java script function is:
function openWindow(url){
window.open(url,'blank','toolbar=no')
Problem:
Since the URL of this new window is
http:// host:portnumber/PrintSummary
Even if I click the "Print summary" link for account2,
being the same URL (http:// host:portnumber/PrintSummary) it accesses the existing page in the cache which is created for account 1.
In href if I just use servlet url as
I get the expected behaviour but then I don't have control on browser appearance and browser window will be with address bar and toolbar.
The only option I could think of was changing URL as follows:
<% String url ="javascript:openWindow('PrintSummary? var1="+ Math.random()+"')";
So that URL is different all the time
Is there any way to solve this problem?
Thanks in advance

I'd definitely try to use a Flex popup... but the
flash.net.navigateToURL method is a simple way to open a popup
window in a new browser. You can pass any data needed by the new
page using the URLRequest and/or URLVariables. The URL you navigate
to could, of course, be another Flex application if necessary. I
use this only when I need to open a popup window on another site,
or an HTML formatter report or something similar.
Concerning yourself with the size of the popup window may be
a bad design choice also. I, for example, have my browser
configured to open all popups in a new tab regardless of sizing
constraints imposed by the designer. If it is absolutely necessary
for you to have control over the size of your popup window, you
should follow the advice given by others and use a Flex
popup.
