This problem is actually a matter of space and time. As you can imagine, if you store all URLs in the memory, the memory will soon be fully occupied. However, if a file exists, you must operate the file each time you read or add it. This performance consumption is relatively large. Therefore, we can quickly think of the reason why cache appears on the computer. My design philosophy
