A FilterChain is an object provided by the servlet container to the developer
giving a view into the invocation chain of a filtered request for a resource. Filters
use the FilterChain to invoke the next filter in the chain, or if the calling filter
is the last filter in the chain, to invoke the resource at the end of the chain.
