Why not implement a small module that sets a DRUPAL_UID cookie and use
that as a cache key? Much simpler than using the session cookie.

Take a look at what the boost module does. I can put up a simple
module that does that. Are you on drupal 6/pressflow?

Ok. Then what you need is a better key. If you have the DRUPAL_UID
cookie then set:

fastcgi_cache_key $http_cookie_DRUPAL_UID$scheme$host$request_uri;

That's a cool idea for a very simple module.

There's a hack here for setting a DRUPAL_UID cookie but it involves
killing kittens: hacking core :)

PS: Here's a very simple module that sets a header, not a cookie. It's
untested YMMV, caveat emptor, and all that:

The .info file is missing.

PPS: Use this key with the above module.

fastcgi_cache_key $http_x_drupal_uid$scheme$host$request_uri;
