I had a similar situation.
In my case the site is 100% php, so in effect anything that comes out 
with Content-Type text/html is php generated and given the nature of the 
site, its not cacheable.

I have also put below my VCL configuration which works fine for me.
Its not much of a high quality configuration, but works for me.

Suggestion, as always, are welcome :)

sub vcl_recv {
        if (req.request == "GET" && req.http.cookie) {
                lookup;
        }
}

sub vcl_fetch {
        if (!obj.valid) {
                error;
        }
        if (!obj.cacheable) {
                pass;
        }
        if (resp.http.Content-Type ~ "text/html") {
                pass;
        }
        if (resp.http.Set-Cookie) {
                insert;
        }
        insert;
}

Hope this helps.
