CORS setup - Cross-Origin-Resource-Sharing on linux Edit htaccess

Edit code and server settings as necessary to allow cross site file serving htaccess and mod_rewrite brief I want to run fonts on child sites where the font folders are located on the parent site using font-face they are displaying in some browsers but not in firefox I have added but his has not worked I need a solution to this I also want images and PDFs which are located on the parent site to be accessed using the child site url so I want to upload PDFs to [login to view URL] and use mod_rewrite or other htaccess code of allow these files to read from [login to view URL],/pdf/[login to view URL] I would also prefer it if images were displayed the same way e.g. [login to view URL] to work with [login to view URL] Any other htaccess suggestions welcome I run a Linux server with Ubuntu
