Send Access-Control-Allow-Origin in http stream #1

Open broesamle opened 7 years ago

Using hyper::net::HttpListener where to setup the access control headers?

streaming in curl seems to work but browser side fails with

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:50123/tenseconds. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

I should mention the relevant branch: https://github.com/broesamle/rust-playpen/tree/streamingchunksB

as @ioctaptceb found out yesterday, currently, no response headers seem to be written at all for the streaming.

Aren't CORS supposed to be sent on an OPTIONS reply done before the blocked one ?
