Varnish + Joomla

I have been attempting to do the following (with no luck so far), since
(from what I understand) the logged in session cookie is a long random hash
name :

[varnish 3.0]

vcl_recv :

set req.http.Cookie = regsuball(req.http.Cookie,
"(^|;\s*)(_[_a-z]+|has_js|base_domain|fbsetting|PHPSESSID)=[^;]*", "");

if ( !(regsuball(req.http.Cookie,
"(^|;\s*)(_[_a-z]+|has_js|base_domain|fbsetting|simpleCart)=[^;]*", ""))){
set req.backend = iamloggedin;

vcl_hash :

if ( !(regsuball(req.http.Cookie,
, ""))){

I know I'm missing something so any way you can assist would be greatly
appreciated. I don't consider myself a varnish expert by any means so I'm
positive there is a way to do this safely. My tests over the course of the
past month have produce mixed results, such as caching the login message of
another user (oops).

We worked with it for quite a bit but I was never too happy with it.

cookie to get it to cache. I'll have to look through my notes.
