Question about Pass

[James Quacinella]

Hello,

 From the man page: "vcl_pass: Called upon entering pass mode. In this 
mode, the request is passed on to the backend, and the backend’s 
response is passed on to the client, but is not entered into the cache. 
Subsequent requests submitted over the same client connection are 
handled normally."

So when running varnishstat, what does 'Cache hits for pass' mean? Sicne 
the above says that pass mode does not enter anything in the cache, but 
it can still use the cache?

thanks for any insight,
james
