<DD>The doFilter method of the Filter is called by the container each
 time a request/response pair is passed through the chain due to
 a client request for a resource at the end of the chain.

 <I>Please note that the response may be null for an event-based method, e.g., ActionEvent.</I>
 <P>
 The FilterChain passed in to this method allows the Filter to pass
 on the request and response to the next entity in the chain.

 A typical implementation of this method would follow the following pattern:<BR>
 <OL>
 <LI>Examine the request</LI>
 <LI>Optionally wrap the request object with a custom implementation to
 filter content or headers for input filtering</LI>

 filter content or headers for output filtering</LI>

 object (chain.doFilter()),</LI>
