variable on userid_domain

[Daniele Melosi]

Hi all,

I'm trying to pass a variable $domain on userid_domain switch but it 
doesn't work:

this is the result:

Set-Cookie: test_cookie=AQAAf0lCkf93nyG2AwMEAg==; expires=Sat, 12-Dec-09 
16:31:59 GMT; domain=$domain; path=/

as you can see domain is $domain

Here my "simplyfied configuration":

server {
        listen   80;
        server_name  localhost host1;

        set $domain "mydomain2";
        if ( $host ~ "host1" ) {
                set $domain "mydomain";
        }

        userid          on;
        userid_name     test_cookie;
        userid_domain   $domain;
        userid_path     /;
        userid_expires  365d;
        userid_p3p      'policyref="/w3c/p3p.xml", CP="CUR ADM OUR NOR 
STA NID"';
         [cut]


how can i solve this (i'd like to avoid to create 2 different server 
definition) ?

Bye
Daniele
