When implementing OpenID Connect (OIDC) for authentication, especially in modern distributed systems, large request headers can become a significant issue. OIDC tokens, particularly JWT (JSON Web Tokens), often contain large amounts of user data, roles, claims, and metadata, all of which are transmitted via HTTP headers. This leads to potential errors if the request headers…

Microservices architecture is a popular model in modern software development due to its ability to break down complex applications into smaller, independent services that communicate with each other through well-defined APIs. This enables greater flexibility, scalability, and faster development cycles compared to traditional monolithic architectures. I recently completed the microservices certification learning path and earned…

In software development, programmers, architects, and developers constantly face challenges like building scalable systems, managing complexity, and ensuring security and maintainability. This is where software patterns become important in design considerations. Patterns offer time-tested solutions to common design and architectural problems, providing a structured approach to solving recurring issues. Rather than reinventing the wheel, they…

IP-based throttling is a common method used to control traffic, prevent abuse, and maintain service stability. However, this becomes complicated when proxies, load balancers, or other intermediaries are involved. In such cases, relying solely on the request’s originating IP may not be sufficient, as client IPs can be hidden behind proxies. Headers like X-Forwarded-For and…

HTTP (Hypertext Transfer Protocol) serves as the foundation of data communication across the web. HTTP headers are an integral part of this protocol, providing essential metadata within HTTP requests and responses. These headers transmit information about the client, the server, the requested resource, and the desired handling of the request. Understanding HTTP headers is crucial…
