 | 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. |
