Which header is used to instruct the browser to install a cookie?

• A. Cookie
• B. Authorization
• C. Set-Cookie
• D. Cache-Control

Answer: (C)

To install a cookie in the browser, the server uses the Set-Cookie header in the HTTP response. This header tells the browser to store a cookie with a specific name and value, and it can include attributes like Domain, Path, Expires/Max-Age, Secure, HttpOnly, and SameSite. Once the browser receives this header, it saves the cookie and sends it back with future requests to the matching domain in the Cookie header. The Cookie header is what the browser sends when making requests, not what creates or installs cookies. Authorization headers carry credentials for authentication, and Cache-Control headers govern caching behavior, not cookie storage.
