What are the Directives of Set-Cookie2 HTTP Header?

The <cookie-name> refers to the cookie’s name, whereas the <cookie-value> refers to the cookie’s value. If the names begin with the letter $, they will not be recognized by any of the computer’s apps.

Comment=<value>

Because cookies are used to retrieve or store data, the value supplied to the comment allows the server to document how it intends to use the cookie.

Domain=<domain-value>

The host to which the cookie will be transmitted is specified by this directive. It’s a directive that can be turned off.

Path=<path-value>

This cookie’s value identifies all the sets of URLs that the cookie has been applied to on the origin server.

Max-Age=<non-zero-digit>

This constraint takes the value in delta-seconds, which is a decimal non-negative integer representing the cookie’s lifetime in seconds. If this life is longer than delta-seconds, the cookie should be discarded by the user.

Discard: By asking the user-agent to discard the cookie, this code deletes or discards it. When the user-agent terminates, it is erased
Secure: This constraint, when written in its default state, will return the cookie back to the origin server without any modifications, preserving the cookie’s secrecy and privacy.
