- Apache vs Nginx Performance: Optimization Techniques
- Key Points Apache and Nginx are both powerful web servers, but their performance features vary; Apache adopts a process-driven model, while Nginx benefits from an event-driven architecture, making it more efficient in handling multiple concurrent connections. Key optimizations for Apache include tuning multi-process modules (MPMs), such as prefork, worker, and event to handle connections more efficiently, and disabling .htaccess where possible to reduce file system performance overhead. For Nginx, key performance enhancements include setting the correct worker process and connection count, leveraging keepalive connections to reduce TCP overhead, and implementing caching policies for faster improvement

- PHP Authorization with JWT (JSON Web Tokens)
- Application authentication used to rely solely on credentials such as username/mailbox and password, and the session was used to maintain user status until the user logged out. After that, we started using the authentication API. Recently, JSON Web Tokens (JWT) are increasingly used to authenticate server requests. This article will introduce what JWT is and how to use PHP for JWT-based user request authentication. Important points Evolution of authentication methods: This article outlines the evolution of user authentication methods, from traditional sessions to using JSON Web Tokens (JWT), highlighting the transition to a more secure and efficient way of user authentication and session management for web applications. .

- How to Use Varnish and Cloudflare for Maximum Caching
- Core points The collaborative use of Varnish and Cloudflare maximizes website caching capabilities and significantly improves loading speed and user experience. Varnish is a powerful cached HTTP reverse proxy, while Cloudflare is a globally distributed network of proxy servers that provide performance and security. The installation and configuration of Varnish involves changing the server default port to 8080 and replacing the default ports in /etc/default/varnish and /lib/systemd/system/varnish.service with 80. Then, Varnish and

- The CSS Reset Contradiction
- For two decades, the web and front-end development field has been using CSS resets (for simplicity, "restart" and "standardization" are included here). I say "about" because Tantek Çelik seems to have started all this in 2004 (you can find me there too), but other authors may have used similar techniques earlier. Basic premise CSS reset is based on three prerequisites: There are differences in how user agents present web pages, i.e. their default styles vary. These differences affect a given website. These differences are important and need to be dealt with. It is obvious that if—or once—all user agents handle CSS the same way, then there is no need for a CSS reset. It is also obvious that

- 5 Techniques for Lazy Loading Images to Boost Website Performance
- In modern web applications, images have become one of the most commonly used content types. Although using background images can improve the visual effect of the application, too large image size will seriously affect the application performance. Even after optimization, images may still take up a lot of space, causing users to wait too long. If users don't get the experience of fast access to content, they tend to lose patience and turn to other websites, so an efficient image loading scheme is crucial. This article will introduce five lazy image loading methods to help you optimize your website and improve user experience. These methods are suitable for all types of images, including background images, inline images, and banner images. Key Points Image lazy loading improves website performance by loading pictures asynchronously, only content that is visible to the page is fully loaded

- Using Background Processing to Speed Up Page Load Times
- Core points Background processing significantly improves page loading speed: transfers heavy tasks to background processing, releases main thread resources, and focuses on page loading, thereby improving user browsing experience. There are two core components of background processing: task queues and worker processes. The application creates pending tasks, while the worker processes extract tasks one by one from the queue for processing. Multiple worker processes can be processed in parallel to speed up. Technology stack selection: Use Beanstalkd task queue to store tasks, Symfony Console components to implement worker processes (as console commands), and Supervisor manages worker processes. Image library optimization: Avoid image scaling on first request (this increases initial loading burden)

- Quick Tip: How to Filter Data with PHP
- Key Points Never trust external input in the application. It is crucial to filter any data contained in your application to prevent attackers from injecting code. The two main types of data filtering in PHP are verification and cleaning. Verification ensures that external inputs meet expectations, while cleaning removes illegal or unsafe characters from external inputs. PHP provides a range of filters for verification and cleaning. These filters can be applied using the filter_var() and filter_input() functions to make your PHP applications safer and more reliable. This article will explore why anything contained in a filter application is so important. In particular, we will look at how to verify and clean external data in PHP

- HTTP/2: Background, Performance Benefits and Implementations
- HTTP/2: Network protocol that significantly improves web page loading speed Core points: HTTP/2 (released in 2015) solves the latency problem of its predecessor HTTP/1.1 by compressing HTTP headers, implementing server pushes and multiplexing requests on a single connection. It is also designed to solve the problem of head-of-team blocking and requires encryption by default. The transition from HTTP/1.1 to HTTP/2 is not without challenges, as backward compatibility is required with existing websites. Any improvement to the protocol must be implemented in a way that does not interrupt the Internet. All mainstream browsers currently support HTTP/2, however, they require that all HTTP/2 requests must be encrypted, which is not a requirement of the HTTP/2 specification itself.
