Forum moving js files to cdn
 

Will there be any problem if I move

Code:
forum/clientscript/vbulletin_facebook.js?v=420
forum//clientscript/vbulletin-core.js?v=420
to CDN.

Will fb login system or vb internal security checks these kind of request from external domain such as CDN?

P.S: I had already moved all other js/css/images to cdn with the help of vbSEO plugin. However only these two file URL hasn't changed and wanted know whether it is safe to move.
