Short answer: you can't

Not so short answer: You can't explicitly set the request header using
only javascript. You'll need to refer to the documentation of your
transport mechanism to do so.

Can you give us more details of what you're trying to do than the OP?

Actually I am working on a Rails application that exposes its REST
API. In other to utilize that API,
the Authorization header would be set to a digital signature. For that
case, we should be able to set the
HTTP headers. Can we do that?
