For Auth/Cookies you need to tell Varnish to cache it, since the things
you're not caching are PHP pages, this is likely the issue.  Here's the
block from my config:

##############
# AUTH       #
##############
sub vcl_recv {
        if (req.request != "GET" && req.request != "HEAD") {
                if (req.request == "PURGE") {
                        if (!client.ip ~ purge) {
                                error 405 "Not allowed.";
                        }
                        lookup;
                }
                pipe;
        }
        if (req.http.Expect) {
                pipe;
        }
        if (req.http.Authenticate || req.http.Authorization) {
                pass;
        }
        # We only care about the "__ac.*" cookies, used for
authentication
        if (req.http.Cookie && req.http.Cookie ~
"__ac(|_(name|password|persistent))=") {
                pass;
        }
        lookup;
}

See if that helps, I'm not 100% clear on all of the syntax in the last
sub-block, or if it's necessary in my case - I too am still learning. ;)
