Ques:- What are the advantages using servlets than using CGI?
Asked In :-
prolifics,
Right Answer:
1. **Performance**: Servlets are more efficient as they run within the server's process, reducing the overhead of creating a new process for each request, unlike CGI.
2. **Resource Management**: Servlets can handle multiple requests concurrently using threads, while CGI creates a new process for each request, leading to higher resource consumption.
3. **State Management**: Servlets can maintain state across multiple requests using session management, whereas CGI does not have built-in support for session management.
4. **Integration**: Servlets can easily integrate with Java APIs and other Java technologies, providing more flexibility and functionality.
5. **Error Handling**: Servlets offer better error handling and debugging capabilities compared to CGI.
