First, the browser, request data, and then it goes through the cache and the server receives the requested data. Now the server will find and send the data and while going through Cache the Cache will take a Screenshot of the data.

So, Now the next time. You are searching for the same data, and the process will stop at the cache level itself. Because the same data is already stored in the Cache, and returns the data from the Cache. Now the requested data will not go to the server. This will reduce the time speed and makes the website faster.
