Cookie-based persistence, or “sticky sessions,” is a method used by load balancers to route a user’s requests during a session consistently to the same backend server, ensuring seamless user experience. It works by assigning a unique identifier cookie to a user’s browser, allowing for continuous interaction with a specific server. This approach is crucial for maintaining session data in web applications.
Load balancer persistence ensures session continuity. Methods include cookie-based, IP hashing, source IP affinity, SSL/TLS session ID, custom headers, parameter-based.
Proxy Server Persistence : Persistence in proxy servers, known as “sticky sessions,” ensures consistent client-server direction, crucial for user experience and session integrity.
A reverse proxy serves as an intermediary between clients and web servers, providing benefits such as load balancing, SSL encryption, caching, security, and compression. Examples include e-commerce sites, corporate websites, video streaming services, API gateways, and content delivery networks. It efficiently manages web traffic, enhances security, and optimizes performance for a seamless user experience.
A forward proxy intercepts outgoing internet requests, providing security, anonymity, and control. It handles requests from clients, masks their IP addresses, caches web content, filters content, and integrates security features. Configuration involves rule setting, authentication, and logging. In a university setup, it authenticates users, caches educational material, blocks malicious sites, and logs web traffic for policy compliance.
