Session 18 | Cookies, Sessions & URL Rewriting Using Servlet

🚀 Java Programming Complete Course – Session 18 Welcome to Session 18 of our Java Web Application Development Series! In this session, we learn three important concepts used for maintaining user information and state in Java Web Applications — Cookies, Sessions, and URL Rewriting. Through practical Servlet examples, you'll understand how data can be maintained between multiple requests and how a web application can identify and manage a user's interaction across different pages or URLs. 📚 Topics Covered ✅ Cookies in Java Servlet What are Cookies? Creating Cookies using Servlet Storing information in Cookies Fetching Cookies from a request Accessing Cookies on another URL/Servlet Reading Cookie name and value ✅ Session Management What is a Session? Why Sessions are required in Web Applications Creating and accessing an HTTP Session Storing information in Session Retrieving Session data across requests Understanding session-based user information ✅ URL Rewriting What is URL Rewriting? Why URL Rewriting is used Passing information through URL Maintaining user information using URL parameters Accessing rewritten URL data in another Servlet 💻 Practical Demonstration ✔ Create and Fetch Cookies using Servlet ✔ Store and Retrieve User Information using Session ✔ Pass Information from One Request to Another ✔ Implement URL Rewriting ✔ Access Data on Another Servlet/URL ✔ Understand Different Approaches to Maintaining State 🔄 Web Application Flow Client Request → Servlet → Store User Data → Another Request → Retrieve User Data You'll also understand the difference between Cookies, Sessions, and URL Rewriting and where these techniques can be used while developing Java Web Applications. 🎯 Ideal For ✔ BCA Students ✔ B.Tech CSE Students ✔ MCA Students ✔ Java Beginners ✔ Java Full Stack Learners ✔ Servlet & JSP Beginners ✔ Internship Students ✔ Placement Preparation 💻 Technologies Used • Java • Java Servlet • Apache Tomcat • Eclipse IDE • HTML • HTTP Cookies & Sessions 🔔 Like 👍 | Share 📤 | Subscribe 🔔 for more Java programming tutorials, Servlet concepts, practical projects, and placement-focused sessions. #Java #JavaProgramming #JavaServlet #Servlet #CookiesInJava #JavaSession #SessionManagement #URLRewriting #JavaWebDevelopment #ApacheTomcat #JavaTutorial #LearnJava #JavaForBeginners #JavaFullStack #BCA #BTech #MCA #CreativeDevelopers
