I am using mod_cache module to enable caching of certain subfolders in VirtualHost section which is mapped to proxy requests to a remote server.
Is there any way to log requests specific to cached files? I want to know:
1. Which files are actually getting cached
2. How many requests are actually getting served from local cache. Effectively how much bandwidth I am saving by serving files from local cache.
3. Is it possible to avoid the default folder structure of the caching, and get a mirror structure instead of the remote path/folder/file structure instead?
4. Is it possible to enable caching for specific file extensions, or by MIME type
