public class ExtensionsServlet
extends HttpServlet

Servlet for starting the extension system when the web server starts. The servlet should be configured with the <load-on-startup>1</load-on-startup> option in the web.xml file. When the servlet is loaded it will initialise the ExtensionsControl class.

This servlet is also acting as a proxy for requests to extension defined servlets. Such servlets are defined in META-INF/servlets.xml in the extension JAR file. A request to a servlet must have the following URL pattern: /extensions/[jar-name]/[servlet-name].servlet
