Description: Fragment caching is a web performance optimization technique that allows specific parts of a web page to be stored, rather than loading the entire page each time a user visits. This technique is based on the premise that many elements of a page, such as images, scripts, or styles, do not change frequently. By saving these fragments in the browser’s memory or on a server, load times are reduced on subsequent visits, thereby improving the user experience. Fragment caching can be implemented through various technologies, such as browser cache, where data is stored locally, or through proxy servers that store versions of pages to serve them quickly to users. This technique not only optimizes load speed but also decreases the load on servers, as it reduces the number of requests that need to be processed. In a world where load speed is crucial for user retention and SEO, fragment caching has become an essential tool for web developers and website administrators.
