Passing another sites cookie on to the client?

Question

We are working with a third party vendor who has a web site
which our CF server will authenticate to on behalf of the client
browser using CFHTTP, and then the third party site replies back to
our CF server with a cookie which we need to pass to the client
browser. The client can then communicate with the third party site
once the client has the cookie. Obviously I can use CFCOOKIE to
create the client side cookie but what's the easiest way to read
the cookie returned to the CF Server?
Thanks,
Steve

Answer 1

I'm not sure this will work? My understanding the nature of
cookies is
that the browser will only return cookies to a domain that
where created
by that domain.
So, even when you get that cookie and write it to the client
(which can
be done), the browser will only ever return that cookie when
the client
is talking to your server. When they move on to the other
server, the
browser will not send the cookie.
This may be outdated, but I thought that is how it works.
I am aware there are some way around this, but I have never
bothered to
learn how to circumvent the methodology. I think it involves
frames,
hidden or otherwise, connected to the remote server. So the
browser
then connects to that server, receives the cookies and sets
them for it.
