Set-Cookie2 HTTP Header: Syntax, Directive, Examples

The Set-Cookie2 HTTP Header is a response-type header that has been obsolete. The Set-Cookie2 HTTP Header provides a means for the client and server to exchange state information. This command is typically replaced by the Set-Cookie HTTP command rather than the Set-Cookie2 HTTP Header. Set-Cookie HTTP is an HTTP response header that is used to communicate cookies from the server to the user agent. Thus, the user agent can send them back to the server at a later time, allowing the server to recognize the user. The Set-Cookie2 HTTP Header has multiple values. The syntax values for the Set-Cookie2 HTTP Header are <cookie-name>=<cookie-value>, Comment=<value>, Domain=<domain-value>, Path=<path-value>, Max-Age=<non-zero-digit>, Discard, Secure.

What are the Directives of Set-Cookie2 HTTP Header?

There are multiple directives that can be put in the Set-Cookie2 HTTP Header. The directives for using Set-Cookie2 HTTP are listed below. 

<cookie-name>=<cookie-value>

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.
