Nope... just either a hidden field in the form or if you are building 
URLs w/ parameters, just add it in.  Very simple stuff.

1. tomcat receive's request
2. if it's an action request like adding an item to a cart, check for 
the presence of the token and compare to the one on the session.
3. On match, change the token in the session so the response can make 
sure it get's in the response hidden field or urls.
    Failing a match, create a new one anyway and store it in the session 
for the response and forward to a safe non-action page like a browse page
4. Build response w/ either the hidden field pre-loaded with the new 
token or urls built w/ the new token.

Nothing so complex as javascript involved.  Just straight server-side
