Sticky Sessions Routing for Traffic Distributor
Sticky Sessions is a routing method that ensures server affinity by "sticking" each user to a specific backend. This method allows users to consistently interact with a single application version throughout their session, maintaining continuity.
How Sticky Sessions Work:
- On a user's first visit, they are routed to a backend based on the server weights, similar to the Round Robin method.
- After the initial connection, the user's browser is assigned to a specific backend using session cookies.
- All subsequent requests from the same user will be routed to the same backend, maintaining consistent interaction with the assigned environment.
Unlike IP-based sticky sessions, which may cause imbalance due to users behind proxies, this platform's cookie-based approach ensures fair and even distribution of users, as each browser is treated as a unique entity.

Use Cases:
- A/B Testing: You can set weights (e.g., 50% / 50%) to distribute unique users evenly between two versions of your application, enabling effective testing.
- Consistent User Experience: Users will always be routed to the same backend until their session expires or the cookie is removed, ensuring a seamless experience across requests.
Key Benefits:
- Persistent routing for user sessions.
- Fair distribution of new users based on server weights.
- Ideal for scenarios requiring server-affinity and continuity of user interaction.
