web HTTP cache performance

Web resource caching: Server-side

The subject of Web resource caching is as old as the World Wide Web itself. However, I’d like to offer an as-exhaustive-as-possible catalog of how one can improve performance by caching. Web resource caching can happen in two different places: client-side - on the browser and server side. In the previous post, I explained the former; this post focuses on the latter. While client-side caching works well, it has one central issue: to serve the resource locally, it must first have it in the

The subject of Web resource caching is as old as the World Wide Web itself. However, I’d like to offer an as-exhaustive-as-possible catalog of how one can improve performance by caching. Web resource caching can happen in two different places: client-side - on the browser and server-side. This post is dedicated to the former; the next post will focus on the latter. Caching 101 The idea behind caching is simple: if a resource is a time- or resource-consuming to compute, do it once and st

HTTP headers forwarding in microservices

Microservices are not a trend anymore. Like it or not, they are here to stay. Yet, there’s a huge gap before embracing the microservice architecture and implementing them right. As a reminder, one might first want to check the many fallacies of distributed computed. Among all requirements necessary to overcome them is the ability to follow one HTTP request along microservices involved in a specific business scenario - for monitoring and debugging purpose. One possible implementation of it
