Servlets can respond to any type of request, and they are commonly used to extend the applications hosted by web servers. Servlet is a server-side Java program module that handles client requests and implements the servlet interface. Now let’s dive deep into Servlets and understand its working mechanism. Here, the client sends an HTTP request and the server answers with an HTML page to the client, using HTTP. And this mechanism allows more users to connect to a given server over a period of time. With HTTP the clients connect to the server to send one request and then disconnect. It is considered as a stateless protocol because it supports only one request per connection.
