javascript - Loading CSS and JS files from another domain and serving resources from consistent URL -

-

i have website grown large , built on super-restrictive platform (sbi). there have follow file structure , put in appropriate folder , upload each , every file through interface manually. have cool html5 template , javascript lot of little files , images way easier upload stuff other domain hosted hostgator using filezilla , refer css , js files sbi site location @ hostgator's domain.

are there potential issues method?

the reason asking because yesterday came across google's article on serving resourcing consistent url: https://developers.google.com/speed/docs/best-practices/payload#duplicate_resources however, might misunderstanding means. when put actual url test @ google's page speed insights here https://developers.google.com/speed/pagespeed/insights advises me serve resources consistent url, in details doesn't complain css , js files, complains facebook only, this:

suggestions page: following resources have identical contents, served different urls. serve these resources consistent url save 1 request(s) and24.3kib. http:// static.ak.facebook.com/.../xd_arbiter.php?... https:// s-static.ak.facebook.com/.../xd_arbiter.php?...

i appreciate reading this. in advance!

serving static content different domain common practice, don't see issues there - it's safe , reliable server using serve it.

the facebook warning mean loading same fb api script twice, or may black magic done fb devs.
