<section name="Request Process Flow">

an incoming request.  This process is largely defined by
the Servlet Specification, which outlines the order
of events that must take place.

A UML sequence diagram of the request process is available

<subsection name="comments">

The Servlet Specification provides many opportunities for
listening in (using Listeners) or modifying (using Filters)
the request handling process even before the request arrives
at the servlet that will handle it.
