Hello Raymond,

Since your VCL code doesn't return anything itself, the default VCL
implementation is run after your own.
The default vcl_recv subroutine will return (pass) if req.http.Cookie
is present, which is the first reason why your page isn't going to be
cached (in fact, it won't even be looked up).
Also, in vcl_backend_response, the returned object won't be cached if
it contains a Set-Cookie HTTP header.

You might want to take care of these cases yourself if you want to
cache those kind of pages, instead of leaving it to the default VCL
implementation.

Regards,
