49		* Proxy that postpones initialization of its target servlet while Magnolia is in update/install-mode. The servlet is
50		* initialized when it sees the first request after the update/installation phase is finished. It looks for an init
51		* parameter named 'servletClass' to find the class of the target servlet. Subclasses can override this behaviour. This
52		* is an alternative to running the servlet in the Magnolia filter chain. Any servlets configured in web.xml need to
53		* have a bypass configured on the Magnolia filter chain that matches its servlet mapping.
54		* <p/>
55		* Initialization of the target servlet will happen after all modules have started.
