## Motivation

According to the [Bunny CDN official documentation](https://support.bunny.net/hc/en-us/articles/8048968124828-Integrating-Perma-Cache-with-your-site), in a full pull zone purge complete purge, the Perma-Cache retains the files but shifts to a new directory structure within the storage zone. If needed, you must manually delete the old cache folder.

**Perma-Cache is expensive, and sometimes you could easily forgot to clear the old cache folder, which will make them take tons of space which will cost your money.**

That’s why I make this webhook so that you can easily integrate to your website to automatically clear the old cache folder whenever you want to trigger it.

## Features

- Immediate cache clearing upon a POST request.
- Scheduled cache clearing at intervals of 1 minute and 3 minutes.
- Logging of cache clearing activities and thread status.
- Thread-safe execution using locks to prevent concurrent cache clearing.
