Local RSS Feed curl Sharepoint

I am new on Xibo.
I use xibo cms on Xampp as server and have connected 2 players win 10 pro.
I use a sheduled curl command for download an rss feed with authrntification from Sharepoint.
My Question: Will rss feeds be downloadet only from the cms and the cms send the feed to the player? Where is the best path to put the rss file?
Sorry my english is not good.

Thank for answers
