servlet

A servlet is a server-side program used to handle requests and generate responses in a web application. When you visit a website, your browser sends a request to the server. The servlet processes this request—such as retrieving data or performing actions—and then creates an appropriate reply, often displaying a webpage. Think of it as a digital assistant on the server that responds to user actions, managing dynamic content and interactions efficiently. Servlets are commonly used in Java-based web environments to facilitate flexible, efficient, and scalable web services.
