Varnish and IPB

[nfn at sapo.pt]

Hello,

I'm trying for some days to setup varnish with IPB (Invision Power  
Board) without success.

The relevant information is:

Cookie member_id: can have -1 (log out users); 0 (guests) and > 0 (members)
Cookies guestSkinChoice|language|mobileBrowser; don't want to cache  
when they are present.
Cookie session_id: php session id; Must be removed

So, in general, I can only cache when member_id is (0|-1) and no other  
cookies are present.
By default, varnish should not cache anything ... I just want to cache  
url's started by:

"/"
""index.php"
"/topic"
"/forum"

Here is a vcl that is not working as expected and I don't know what is  
wrong. I using varnish 3.

Can someone give me some help?

Thanks
