A reverse proxy acts as an intermediary server between clients and back-end servers. It receives requests from clients, forwards those requests to the appropriate back-end servers, and then sends the responses back to the clients. Reverse proxies are often used for load balancing, security, and improving performance.
1. Increased scalability and flexibility: Reverse proxies can distribute client requests across multiple back-end servers, providing increased scalability. They also allow for easier modification and updating of the back-end infrastructure without disrupting services, as changes can be made to the back-end servers without affecting the clients directly.
2. Reduced back-end server resources: By distributing client requests across multiple back-end servers, a reverse proxy can balance the load, reducing the burden on individual back-end servers and optimizing resource utilization.
3. Session persistence not important: In some scenarios, session persistence is critical to maintain user state across requests. However, in this case, session persistence is explicitly stated as not important. This means the reverse proxy doesn't need to manage sticky sessions, further simplifying the setup.
