A servlet is a Java programming language class used to
extend the capabilities of servers that host applications
accessed via a request-response programming model.

Although servlets can respond to any type of request, they
are commonly used to extend the applications hosted by Web
servers. For such applications, Java Servlet technology
defines HTTP-specific servlet classes.

init()
service()
getServletConfig()
getServletInfo()
destroy()
