Advanced Jakarta Servlets: Implement Basic Filters

Servlet filters are powerful for handling tasks like authentication, logging, input validation, and compression. They work their magic on both incoming requests and outgoing responses, allowing you to perform pre- and post-processing without modifying the core servlet code.In this course, learn about Java Servlet filters and how they tackle cross-cutting concerns in web applications. Discover how filters can intercept requests and responses to apply consistent logic, such as authentication, logging, and content modification. Next, explore how to chain multiple filters and control their execution order and use annotations to configure filters directly in your code, streamlining the setup process. you’ll also study how filter sequencing impacts behavior, testing the order in which different filters are applied. Finally, discover how filters actively process both incoming requests and outgoing responses, and configure multiple filters to work in sequence, with each one addressing a specific concern.
