That is really how it should be.  A second header of the same name isn't
really allowed in the specification.  I realize that some CGI tools
successfully add it in, and browsers do try to handle multiples, but it
isn't supposed to happen.

Two viable options :

Print one header with a 302 in order to force the browser to make a
second request that we can get the other cookie into.

Respond with javascript that sets the cookie for the second domain.
