A cached page is a temporary duplicate of a specific web page, stored either on a local device or on an external server. Browsers and web services utilize caching to significantly accelerate page loading times.
If you frequently revisit the same websites, your web browser will store a temporary copy of some of their data. It does this so that you are not required to fully reload all elements of the page every time you access it. This process is known as browser caching, a common technique that helps to reduce latency while navigating the web.
Other forms of page caching involve the use of Content Delivery Networks (CDN). A CDN is a service that temporarily stores copies of web pages in data centers located across specific geographical regions. The purpose of a CDN is to redirect incoming visitors and serve them the cached versions of your website. Employing a CDN can alleviate the resource load on your primary servers and improve page speed.
When setting up caching mechanisms for your website, it is crucial to establish clear expiration deadlines. This ensures that client browsers know precisely when to discard the stored cache and fetch a completely fresh copy of your website, preventing users from viewing outdated material.
