Businesses often face challenges in managing user sessions consistently across multiple domains, especially when they host various apps and products. This blog explains how Cloudflare Workers and Descope can be used to unify session management seamlessly across these domains. Cloudflare Workers are lightweight, serverless functions that can intercept, modify, and forward web requests on Cloudflare's global network, making them ideal for creating a proxy between client requests and Descope services regardless of the originating domain. The blog outlines the process of setting up Cloudflare Workers, including configuring domains and handling cookies and CORS headers to ensure that session cookies remain correctly set for clients’ domains. By combining Cloudflare Workers and Descope, businesses can maintain secure refresh tokens across apps on different domains, streamlining session management and providing a consistent user experience. This integration not only simplifies backend complexities but also enhances the frontend experience, illustrating a potent approach to managing user sessions across diverse web and mobile applications.
