There are cached or stored pages in Google servers, the cache is shown as (cache:xyz.com) or (cache://play.com). The caching takes place when Google Bot visits the web page. To load a website more quickly browsers store images, pages, graphics, Java Scripts, and HTML more quickly. This process of storing by the web browser is termed caching. Usually, these are stored temporarily but the time of storage can be controlled. Not only web browsers but DNS Servers also store data to make retrieval faster or increase latency. Increased delay is due to difficulty in the resolution of the DNS Servers.
Browsers usually store data on the hard drive of the devices. Before we proceed further lets us know:
How do I clear my web cache?
Android:
1. On your Android phone or tablet, open the Chrome app.
2. At the top right, tap More.
3. Tap History Clear browsing data.
4. At the top, choose a time range. To delete everything, select All Time.
5. Next to “Cookies and site data” and “Cached images and files,” check the boxes.
6. Tap Clear data.
The time to live of storage or TTL when expires is until the hard drive storage capacity is full. Clearing the cache restores the storage capacity. After clearance when the user calls for the website, all elements have to be loaded again and this could slow the website for the first time.
