OIDC Large Headers – How to conquer 400 errors
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…

Understanding Microservices Architecture – Design Better
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…

Factory Method Design Pattern – Design Better
The Factory Method design pattern is one of the most well-known and frequently used design patterns in software development. It falls under the category of creational patterns, which focus on ways to instantiate objects. The primary goal of the Factory Method is to provide a flexible and scalable way to…

The Singleton Pattern: Know how to manage Resource Effectively
Imagine a large, bustling company where several teams work on critical projects at different locations. Each team needs to send important updates, requests, or urgent messages back to the head office regularly. There is only one communication device available to all teams—a complex and old-fashioned piece of equipment, like a…

Essential Software Patterns: Design Better
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…

Throttling and the Proxy: How to Securely Throttle Traffic
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…

HTTP Headers: Not Just Metadata, Your Security Shield
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.…

Input Validation in Microservices: Know how to secure the gates
In the world of microservices, the shift from traditional monolithic applications brings increased complexity to input validation. Microservices must rigorously validate data at every entry point, considering both client mistakes and malicious intent. This approach acts as a shield against attacks and safeguards data integrity, reputation, and user trust.

Spring Dependency Injection: Annotation vs XML config
In the world of Java and Spring Frameworks, Dependency Injection (DI) plays an important role in decoupling software components, making them more modular and testable Over the years, Spring has evolved to provide two main mechanisms for DI: annotation-based XML configuration. This article explores both approaches in detail, providing examples…

Version Notation in package.json
When working with Node.js, understanding the version notation in your package.json file is crucial for the stability and efficiency of your projects. This blog post delves into the intricacies of Semantic Versioning (SemVer) and how different symbols in your package.json can significantly impact your project’s dependency management. Semantic Versioning (SemVer)…
