I think you can do it with map. Untested:


map $http_cookie $logged_in {
default 0;
~SESS 1;
}

Define two locations each with a different cache (anon/authenticated):

The default cache is the anon:

location @anon-cache {
error_page 418 @auth-cache;
if ($logged_in) {
return 418;
}
userid_expires 0s;
... # fastcgi cache stuff for anon users
}



location @auth-cache {
# set the user id expires here to a positive value
# fastcgi cache for authenticated users
}


I never played with the userid module. So...
