WpFastest Cache & FTP upload

Hi all,

I hope you’re fine.
I’ve recently installed WPfastestcache and made the additional configuration with DNS CloudFare.

We use our FTP to upload and update a PDF file with our catalogue for our clients.
It seems to me that I now have to delete manually the cache each time for the updated PDF to show up and not the cached version.
Even if disable most of the cache settings on WPFastestCache, I still have to manually delete the cache to get the most recent update.

So I have two questions :

– Is this normal? Or should I use a different cache configuration ?
– Even by excluding the repertoire where is the PDF in question, it continues to be cached.

To be clear, it really is about this specific PDF file and its upload by FTP, I don’t have any other problems.
Every bit of help could be useful for me.
Thanks!
