report progress in a long running function (say POST)

[Simon Chen]

Hi all,

I am wondering how I can report progress back to the client about a
long-running function?

Say I have:

@POST
@Path("/setup")
Response setup(...) {
  ...
}

The setup function may take a long time to finish. Returning a
Response.ok() might be fine, but I'd prefer the client to see
something in the middle...

Thanks.
