Where can webpages be cached?

Webpages can be cached in several locations, including the user's web browser, which stores copies of visited pages for faster access. Additionally, content delivery networks (CDNs) cache webpages on servers distributed globally to reduce latency and improve load times. Server-side caching can also occur, where web servers store frequently accessed content in memory or on disk. Lastly, proxy servers can cache webpages to serve multiple users more efficiently.
