Description

AFAIK CORS requirements can be enforced by compliant WebSocket implementations such as Atmosphere and that any secure WebSocket server should be capable of implementing CORS filters.

The question is: can we reuse CXF JAX-RS CORS filters when working with web sockets and when we need to worry about it. I guess it is only an upgrade request issue, once the upgrade is done using a wss protocol we have a secure channel in place.

If so then CXF filters will likely do as they will reject the initial upgraded request if it does not meet the CORS restrictions, but the transport may need to discard the upgraded connection in such cases.
