localization recommendation for tomcat

[HAVENS,PETER (HP-Cupertino,ex3)]

I am looking for a recommendation for serving localized HTML content via
tomcat.   I am looking to have Tomcat provide the most accurate HTML file
based on the locale of the browser.  The Apache web server handles this
nicely and I would like to implement the same functionality in tomcat 4.1.x.
For example, when a request comes in for index.html and the browser locale
is french [fr], if the server has an index.html.fr file and an index.html.en
file, I would like it to serve the French version.  
 
I am not looking for a complete solution but rather a pointer for a
developer.  I have read a little about turbine services and servlets
filters.  Can someone make a recommendation for the most applicable
technology for this feature?
