HttpServletResponseWrapper: Java Servlet API for Enhanced Response Handling

The "HttpServletResponseWrapper" is a class in the Java Servlet API that provides a convenient way to extend the functionality of the "HttpServletResponse" class. \n\nIt is a wrapper class that implements all the methods of the "HttpServletResponse" interface and delegates the actual implementation to the wrapped "HttpServletResponse" object. This allows developers to modify or enhance the behavior of the response object without directly modifying the original response object.\n\nBy extending the "HttpServletResponseWrapper" class, developers can override specific methods to provide custom behavior. For example, they can override the "getOutputStream()" method to intercept the response output stream and perform additional processing before passing it to the original response object.\n\nThe "HttpServletResponseWrapper" is commonly used in web applications that require custom response handling, such as modifying response headers, adding additional response content, or implementing response caching.
