You could also put the cookie info in the URL you redirect to (as a
query string), and make your handler look for it there if the cookie is
missing.

I have tried this but with no success. I'm running NS4.7 on RH6.1. What I
found when I use Apache::Debug::dump() is that if I use a simple string as
the $cookie, the cookie is passed along redirect. However if the $cookie
is an object of CGI::Cookie, it is missing in the redirect request.

Try changing to $r->err_headers_out.  Details in the eagle book.

This is a misfeature of some browsers. (Particular versions of
Internet Explorer, if I remember correctly.)

Some people have reported success with some browsers depending on
the order the headers appear, but the most bullet-proof solution
is to do a redirect with a header or meta-tag refresh instead of
an redirect. (Which is definitely not as user-friendly, but works
for all cookie-enabled browsers that I've come across.)

So you'd want to do something like:

  $r->headers_out->add('Set-Cookie' => $cookie);
  $r->headers_out->add('Refresh' => "0; url=$location");
  $r->print("Sending you here.");
  return OK;
