You should not send name/password in clear text. You should send it using
HTTP+TLS == HTTPS! My three suggestions should be used together.
The more salient point is that a REST client may or may not like cookies,
because you cannot, for example, issue multiple requests in parallel until
you've first done the stateful, cookie-generating, initial server

HTTPS has had some performance problems with an additional round-trip during
connection negotiation for TLS. For browsers that re-use the connection (all
HTTP/1.1 browser), this is not much of a problem. However, our friends at
Google have actually done a lot of research in how to front-load the
necessary packets, so that you can recude the negotiation overhead to close
to zero, without a change in protocol! It's quite fascinating. For an
initial look, check out:



Americans might object: there is no way we would sacrifice our living
standards for the benefit of people in the rest of the world. Nevertheless,
whether we get there willingly or not, we shall soon have lower consumption
rates, because our present rates are unsustainable.
