High-availability agent communication

Agents communicate with the server over HTTP or HTTPS. These modes of communication are handled differently in a high availability scenario.

HTTP or HTTPS communication

A standard load balancer handles HTTP or HTTPS server-agent communications. Authentication is run on every request; any server can run validation for any request. You configure HTTP or HTTPS server-agent communication when you configure your cluster of servers. See Setting up clusters of servers.

In case of server failure, user-server authentication must be redone unless the ‘remember me’ cookie is used.
