In this guide, we’ll configure both, with a safe cache key, session-cookie bypass, cache locking and stale serving. https://www.toidang.xyz/posts/2021/08/06/page-caching-implementing-page-caching-in-a-rails-application-with-redis/ Fri, 06 Aug 2021 18:08:55 +0700 https://www.toidang.xyz/posts/2021/08/06/page-caching-implementing-page-caching-in-a-rails-application-with-redis/ Serving whole pages from a shared cache breaks Rails forms, because every visitor receives the CSRF token that was rendered for someone else. In this post, we’ll cache public pages with Rack::Cache backed by Redis and look at two ways to keep CSRF tokens working: fetching a fresh token with JavaScript from a small uncached endpoint, and a Rack middleware that injects one on the server. https://www.toidang.xyz/posts/2021/08/05/page-caching-leveraging-page-caching-with-varnish-in-rails-applications/ Thu, 05 Aug 2021 18:08:55 +0700 https://www.toidang.xyz/posts/2021/08/05/page-caching-leveraging-page-caching-with-varnish-in-rails-applications/ Varnish can cache whole Rails pages in memory and serve them without touching the application, but only if Rails tells it which pages are safe to share. In this article, we’ll let Rails mark public pages with Cache-Control, configure Varnish to honour those headers without leaking one user’s page to another, and add PURGE/BAN invalidation. https://www.toidang.xyz/posts/2021/08/04/page-caching-strategies-for-web-performance-optimization/ Wed, 04 Aug 2021 18:08:55 +0700 https://www.toidang.xyz/posts/2021/08/04/page-caching-strategies-for-web-performance-optimization/ Page caching is a technique used to improve the performance of web applications by storing the entire HTML output of a page and serving it directly from the cache for subsequent requests. This eliminates the need to generate the page dynamically on each request, reducing server load and improving response times. In this article, we’ll explore the concept of page caching, the HTTP caching basics it relies on, and the main places a full page can be cached, plus related techniques that cache smaller pieces. https://www.toidang.xyz/posts/2021/04/07/using-redis-in-rails-applications/ Wed, 07 Apr 2021 18:08:55 +0700 https://www.toidang.xyz/posts/2021/04/07/using-redis-in-rails-applications/ Redis is an in-memory data structure store known for its speed and flexibility. It serves as a high-performance database, cache, and message broker, offering data structures such as strings, hashes, lists, sets, and sorted sets. This article covers how Rails applications use Redis for caching, sessions, background jobs and counters, how to set up Rails’ built-in Redis cache store, and when Rails 8’s database-backed defaults make Redis optional. https://www.toidang.xyz/posts/2021/02/08/understanding-a-b-testing-enhancing-decision-making-in-web-development/ Mon, 08 Feb 2021 18:08:55 +0700 https://www.toidang.xyz/posts/2021/02/08/understanding-a-b-testing-enhancing-decision-making-in-web-development/ A/B testing, also known as split testing, is a method used to compare two or more versions of a web page or application to determine which one performs better in achieving a predefined goal. In this article, we’ll look at the concept, how to implement it in Ruby on Rails with the Split gem, and how to read the results without fooling yourself. https://www.toidang.xyz/posts/2020/07/16/understanding-load-balancing-at-different-network-layers-a-comprehensive-overview/ Thu, 16 Jul 2020 18:08:55 +0700 https://www.toidang.xyz/posts/2020/07/16/understanding-load-balancing-at-different-network-layers-a-comprehensive-overview/ In modern web application environments, load balancing plays a critical role in distributing traffic across multiple servers to ensure optimal performance, reliability, and scalability. Load balancing techniques and tools are deployed at various network layers, each with its own set of advantages and disadvantages. In this article, we’ll explore different types of load balancing at different network layers and provide examples. https://www.toidang.xyz/posts/2020/03/07/understanding-nginx-real-ip-module-importance-and-configuration/ Sat, 07 Mar 2020 18:08:55 +0700 https://www.toidang.xyz/posts/2020/03/07/understanding-nginx-real-ip-module-importance-and-configuration/ In the realm of web servers, accurate logging of client IP addresses is crucial for security, analytics, and compliance purposes. However, when Nginx is deployed behind a reverse proxy, load balancer, or CDN, the IP addresses logged may not reflect the actual client IP addresses. This is where the Nginx Real IP module comes into play. https://www.toidang.xyz/posts/2020/03/02/understanding-sidekiq-a-powerful-background-job-processing-solution/ Mon, 02 Mar 2020 18:08:55 +0700 https://www.toidang.xyz/posts/2020/03/02/understanding-sidekiq-a-powerful-background-job-processing-solution/ In today’s web development landscape, handling background job processing efficiently has become crucial for building robust and scalable applications.
