"Figure 3-1 shows how the servlet container invokes filters. On the left is a scenario in which no filters are configured for the servlet being called. On the right, several filters (1, 2, ..., N) have been configured in a chain to be invoked by the container before the servlet is called and after it has responded. The web.xml file specifies which servlets cause the container to invoke the filters."
