It resides in a servlet container, which manages servlets, maintains their lifecycle, and handles client requests and responses. The servlet context is a global object that provides information about the environment in which the servlet is running. The servlet request heap and servlet response heap are memory areas where the servlet container holds request-related and response-related data for a specific servlet instance. Therefore , the correct answer options is a)
Step-by-step explanation:
A servlet is a Java program that processes client requests and generates dynamic web content. It resides in a servlet container which is a part of a web server. The servlet container manages servlets, maintains their lifecycle, and handles client requests and responses.
The servlet context is a global object that provides information about the environment in which the servlet is running. It contains attributes shared across multiple servlets and allows them to communicate with each other.
The servlet request heap refers to the memory area where the servlet container holds request-related data for a specific servlet instance. This includes parameters, headers, cookies, and other data sent by the client.
The servlet response heap refers to the memory area where the servlet container holds the data required to generate the response for a specific servlet instance. This includes the response status, headers, and body.
