You would need your own server I believe. Again it depends a lot on what you are trying to do exactly, which you haven't given very many details. Though I believe the answer to your specific question is below so you should accept it. You cannot embed a private file. If you have another question you should open a new question. Though maybe softwareengineering.stackexchange.com is a better place for general questions about how to design your site. — iansedano 47 secs ago

you might want to go through softwareengineering.stackexchange.com/questions/144787/… and stackoverflow.com/questions/23852586/… — Suraj Rao 49 secs ago
