I followed the instruction for adding CORS header but it doesn't work

[ikanlangit]

I followed this instruction.

https://support.cloudflare.com/hc/en-us/articles/200308847-Using-cross-origin-resource-sharing-CORS-with-Cloudflare#4vknA9IbgW57oiclaPv4QP

I have added Access-Control-Allow-Origin header on the origin server.
And I tried this approach:

• Use the single-file purge API to specify the appropriate CORS headers along with the purge request.

But it doesn’t work.
My files still don’t have CORS header.

Including the header (as stated by the API docs) is for purging a specific cache key.

You will need to add the header(s) at your origin server or with Cloudflare Workers (Example here: CORS header proxy · Cloudflare Workers docs)
