Opening one struts app from another without sharing sessions

[Danny Collins <dc...@maine.rr.com>]

Hello everyone,
            I was wondering if anyone had any idea how to open one
struts application from another struts application without sharing a
single session?
 
            In my main app, we have the need to launch a small separate
application, that is also struts based, but all I can seem to find to
use is window.open and  in IE that ends up sharing session data, which
is highly undesirable. 
 
Any ideas,
 
TIA
Danny
