Why can Chrome get file, but not Safari?

The URL

Open this url in Chrome is all fine, but when open it in Safari, some files can't get forever.

OK in Chrome:

BAD in Safari:

As you can see, all plist file and ExportJson file can't get in Safari. But they all exists in server.

Like faceshow_10.plist, it's url is http://ift.tt/1B1lWOS.

And in Chrome is all ok.

Question:

Why this happen? And How should I fix it?
