A servlet is lazily loaded in servlet container of web or
application server. This means, a servlet is not instantiated
or initialized in servlet container as long as it has not been
requested for the first time. A servlet can be preloaded and
preinitialized with the help of <load-on-startup> of web.xml
(deployment descriptor) file.The preloading of a servlet
before any user request is called servlet preinitialization.

Servlet can loaded in servlet container of web or
application server at the time of first request sent to
that servlet.
If we want to preinitialized the servlet by using <load-on-
startup> tag(Aritten in web.xml). If we use that tag,
servlet is intialized at the time of server start.
