Session unique identifiers are passed to the web API using which HTTP header option?

Using session unique identifiers in web APIs is essential for maintaining the state of a user's session, especially in security contexts. The correct choice, where session unique identifiers are passed to a web API, is associated with the HTTP header option "X-chkp-sid."

This specific header is designed to hold session IDs that are generated during the authentication process. When a client successfully logs in to a Check Point device or service, a unique session ID is issued. The client must then include this identifier in subsequent API requests using the "X-chkp-sid" header. This ensures that the requests are correctly associated with the authenticated session, allowing the server to maintain context and state.

The other options do not serve this purpose. For instance, "Accept-Charset" specifies the character encoding that the client can process but does not relate to session management. Similarly, "Proxy-Authorization" is used for credentials that authenticate a user to a proxy server, and "Application" doesn't pertain to session identifiers. Understanding the specific use of headers in API communications is crucial in the context of security and access management.
