<P>
A <code>FilterChainResolver</code> can resolve an appropriate <CODE>FilterChain</CODE> to execute during a
<code>ServletRequest</code>. It allows resolution of arbitrary filter chains which can be executed for any given
request or URI/URL.
<p/>
This mechanism allows for a much more flexible FilterChain resolution than normal <code>web.xml</code> servlet filter
definitions: it allows arbitrary filter chains to be defined per URL in a much more concise and easy to read manner,
and even allows filter chains to be dynamically resolved or constructed at runtime if the underlying implementation
supports it.
