Question around Gzip static and CDN

I am sure the CDN supports gzip. So in case if I configure nginx with
gzip ( and not gzip_static ) and there is only test.js , then the CDN
works fine ( the CDN response headers contains gzip ). This issue seems
quite specific to CDN and having only test.js.gz on my server ( with
nginx configure as gzip_static )
