Auto Extend the cached file's longevity if the user views it before it expired.

## Auto Extend Longevity (Maybe Boolean)

an option to auto-extend the cached file's expiration date or longevity.

### Contextualize the feature
It would be great, since, for example, like my application, I want to extend the longevity of a cached file every time a user views it. So, that it wouldn't cost me a lot with database: Bandwidth.

### Describe the feature
Maybe add an option to enable the auto-extend longevity option, so that every time a user views a file its longevity time is extended. For example, I've set my file's longevity to 3 days. If the user views this file on day 2, a day before expiration, the expiration date will be extended by 2 days. Now the file would expire 3 days after the user viewed it. It would continue extending the expiration date and longevity unless a user hasn't viewed this file for 3 consecutive days.

This would help greatly if the application we're implementing it in is a social media type or e-commerce. We can cache the images and auto-extend their expiration date every time a user views them. But please make sure that the file is removed after the expiration date is over.

尚未确定任何文件、测试或入口点。首先在仓库中定位缓存过期和驱逐路径，然后明确该选项的 API 及续期语义。完成的标准是：已查看的文件会续期，而未查看的文件会在过期后被移除，并且测试覆盖这两种行为。
