Description: Web caching is a process that involves storing copies of web pages in temporary storage systems, with the aim of reducing load on servers and improving access speed for users. This mechanism allows browsers or intermediary servers to serve stored copies instead of requesting the same information from the original server each time, resulting in faster load times and a smoother user experience. Web caching can be implemented at the browser level, where elements like images, scripts, and stylesheets are saved, or at the server level, where complete responses to HTTP requests are stored. Additionally, the use of content delivery networks (CDNs) is also based on the principle of caching, distributing copies of content across multiple geographic locations to optimize access. In a variety of computing environments, web caching plays a crucial role in performance optimization, allowing applications to scale efficiently and reduce operational costs by minimizing direct requests to origin servers.
