I am trying to request a page that requires 2 different sets of authentication for 2 different realms. Sending the Basic Authorization in the header works for the first set however I can not get the credentials to pass for the second realm. 
$uri = "HTTPS://$host:$port/path";
$ua = new LWP::UserAgent;
$h = new HTTP::Headers;
$h->header('Authorization' => "Basic $authinfo");

$request = new HTTP::Request('POST', $uri, $h, $content);

$ua->credentials("$host:$port",'realm2',$userid,$password);
$response = $ua->request($request); 
print $response->status_line; 
print $response->as_string;

When the ua->credentials line is included the authentication doesn't even work for the first realm. If that is excluded the first realm authenticates but the second realm fails. Is there a way of sending 2 sets of credentials for 2 different realms.
