URGENT!!

hi all,
my code works in the following manner.
i have a central controller which is a servlet.
i am using the model 2 architecture (MVC) pattern.
all request go to this servlet which sees in the properties file and calls the corresponding business object(logic which is a class).
This class returns a XML file which i have to display on the browser.
my problem is suppose another request comes before the earlier xml file is thrown on the browser, then this file is replaced.
i thought of placing this file in the session..
Is there any other better way to do this..
Certainly all u champs out there can help me on this..
Thanx in advance
Chhaya

I was just wondering,
so you must be having some kind of code like this...
void someMethod(){
try{
id= request.getParameter(<something> );
BusObj busObj = busobjHash.get(id);
...
//render it on browser using
//requestdispatcher?

}
one simple solution could be to synchronize someMethod() so that all the requests are sent in a serialized manner
But this will bring down the performance?
prav.
