问题
I cannot get azure blob storage hosted fonts exposed via azure cdn working in IE or Firefox.
I believe this is because of @font-face cross-domain issues (CORS) and the normal solution is to add an Access-Control-Allow-Origin header. I know that most CDNs now support this but am assuming that Azure still doesn't. Can anyone confirm this?
If this is the case, are there any workarounds?
回答1:
This is no longer true, azure supports CORS

and a little guide to adding fonts to your azure cdn:

回答2:
The CDN doesn't modify the headers from the origin, so it responds with whatever headers blob storage emits. Blob storage does not support CORS headers.
I'm surprised to learn that @font-face has cross-domain restrictions, but it appears that you're right (for Firefox and IE).
If you have that option, you could put the fonts on a cloud service (rather than blob storage) behind the CDN and emit the right headers there.

Your assessment is correct.
As a workaround, our company is utilizing Google storage (which supports CORS).
I would also suggest voting up this issue so the Azure team knows how many people are running into it.

I can use fonts, without setting up the CORS option anyway. I'm linking my fonts directly to the blob storage, and not a CDN, since this one does not supports the CORS from the blob.
