Jetty 6 ships with a bundle of servlets that interacts with the key classes. Mostly they can be found in the org.mortbay.servlet package. Here is a list of servlets playing a major role in running and maintaining the Jetty server:
The CGI servlet class extends the abstract HttpServlet class. When the init parameter is called, the cge bin directory is set with the cgibinResourceBase otherwise, it will default to the resource base of the context. There are three parameteres that the cgi bin is using:

commandPrefix - this is the init parameter that is obtained when there is a prefix set to all commands directed to the method exec |
This class implements the Filter interface that is called by the web container. It acts as a decoder of the mulitpart/form-data stream sent by a HTML form that utilizes a file input item. Any files that is sent are stored to a temporary location and there will be a file object added to the request which will act as an attribute. It is made available that other values through the usual getParameter API and the setCharacterEncoding mechanism is respected when converting bytes to Strings.
This is a simple servlet which extends the abstract class HttpServlet that displays the code 500 error message "JSP support not configured."
This is an experimental servlet which implements the Servlet interface. It acts as an authorized servlet on behalf on another running servlet. This seems not to be a substitute for the running servlet but provides a mirror for the service.
Implemented by the Filter interface, the ThrottlingFilter servlet concern is to protect a web application from having to handle an unmanageable load. This accounts when there is a server that holds one application with standardized resource restrictions and with this will be controlled by lowering or limiting the size of the ThreadPool. But when there are several applications in service or a single app having different resource requirements to different URLs, then the ThrottlingFilter comes in and guiding the number of requests being handled by Jetty.

maximum - determines the maximum number of requests that may be on the filter chain anytime |
This is another serlvet which also implements the Filter interface. This forwards any servlets to the necessary welcome display of an application when serviced.
Found in the org.mortbay.jetty.servlet package, this servlet implements the ResourceFactory interface and extends the HttpServlet abstract class. This is the default servlet of Jetty usually mapped to / provides handling for static content, OPTION and TRACE methods for the context. The MOVE method is allowed if PUT and DELETE are allowed.
