mod_perl not sending cookies

[Andrew Fritz]

I'm using Apache:AuthCookie. I have set up a basic test site. It appears 
that AuthCookie never send the cookie even though the call to:
   $r->err_headers_out->add("Set-Cookie" => $cookie);
is there. If I modify the call to include a simple cookie:
   $r->err_headers_out->add("Set-Cookie" => 'a=b');
it works.

The value of $cookie is:
jza70AuthHandler_JZA70=\"Thisisatest\"; expires=Tue, 11 Mar 2003 
06:33:50 GMT; path=/thisisatest; domain=jza70

The expires field is from a log of a few days ago, but was valid (about 
24 hours in the future) when it was sent.

Any thoughts are apreciated.
