Why should it be in singleton?

[eunwoop]

it is recommended to use HttpProxyCacheServer as singleton,
but anyone knows why?
I want to shutdown after video is gone, but then HttpProxyCache should be re-created after that.

Using HttpProxyCacheServer as a singleton is recommended due to its design for resource efficiency, thread safety, and caching consistency. Repeatedly creating and destroying instances can lead to redundant initialization, resource wastage, and potential performance issues.
As a singleton, it ensures cached video data remains consistent and avoids issues like file descriptor leaks or unclosed resources. If you want to shut down the server when a video is no longer needed but still allow re-creation, you can implement a restartable singleton. This involves initializing HttpProxyCacheServer only when needed and providing a method to stop its operations and clean up resources after video playback ends.
By maintaining the proxy as a static reference, you can restart it when required, combining the benefits of efficient resource management with controlled lifecycle handling. This approach allows you to optimize performance without compromising flexibility.
