/**
 * The <code>doFilter</code> 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. The FilterChain passed in to this
 * method allows the Filter to pass on the request and response to the next entity in the
 * chain.<p>
 * A typical implementation of this method would follow the following pattern:- <br>
 * 1. Examine the request<br>
 * 2. Optionally wrap the request object with a custom implementation to
 * filter content or headers for input filtering <br>
 * 3. Optionally wrap the response object with a custom implementation to
 * filter content or headers for output filtering <br>
 * 4. a) <strong>Either</strong> invoke the next entity in the chain using the FilterChain object (<code>chain.doFilter()</code>), <br>
 * * 4. b) <strong>or</strong> not pass on the request/response pair to the next entity in the filter chain to block the request processing<br>
 * * 5. Directly set headers on the response after invocation of the next entity in the filter chain.
