Backend Server

Backend server contains the following fields:

• Balance: Specify which load balancing method can be used in this Backend Server.
• Timeout: To specify the Session timeout between the nBalance and the Backend Server.
• IP Persistence: IP persistence, also known as session persistence or sticky sessions, is a feature in nBalance that ensures that a user's requests are consistently directed to the same backend server during a session. This is important for applications that store session data on the server side and need to maintain continuity for a specific user throughout their interaction.
• Cookie Persistence: Cookie persistence ensures that a user's requests are consistently directed to the same backend server during a session. We use these applications to store session information in cookies and need to maintain continuity for a specific user throughout their interaction.
• Server name: server name is the FQDN of the real/backend servers and the IP address is the real/backend servers. The port which is active on the real server.
• HTTP Check: "https check" refers to a health check mechanism where HAProxy actively attempts to establish a secure (HTTPS) connection to a backend server to verify its availability and responsiveness.
