This page describes the process used by Tomcat to handle
|
|
an incoming request. This process is largely defined by
|
|
the Servlet Specification, which outlines the order
|
|
of events that must take place.

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.
