Handling cookies

I am trying to configure Varnish to cache everything except a few specific URLs that need to be passed back to Apache/PHP. This is what I have so far

sub vcl_recv {
  if (req.request == "POST"
        || req.url ~ "^/my-details"
        || req.url ~ "^/cart"
        || req.url ~ "^/billing-details"
        || req.url ~ "^/delivery"
   ) {

   if (req.request == "GET") {
      unset req.http.cookie;
      unset req.http.Authorization;
  //default action, just in case
sub vcl_fetch {
 if (req.request == "GET") {
     unset obj.http.Set-Cookie;
     set obj.ttl = 30m;

sub vcl_hash {
  if (req.http.Cookie) {
   set req.hash += req.http.Cookie;

What I'm finding are two issues:

1. javascript and css files are not being cached (I am monitoring using   varnishtop -b -i TxURL ) even though my vcl_recv would appear to be caching everything that is pulled via GET

2. The non-cached pages ( e.g. /my-details accessed via GET) do not seem to pick up all of the cookies generated in PHP, yet if I call the same page via Apache directly ( by passing Varnish) the cookies are found fine.

If someone could point me in the right direction that'd be much appreciated.

Thanks, David
