return(refresh) from vcl_hit / Re: [PATCH] Add "hash_always_expire" option to treat any existing objects as expired

[Dridi Boukelmoune]

Hi Nils,

misread everything including the documentation,  your email and the
discussions on IRC.

I will document the return(fetch) in 4.0 though.

Cheers,
Dridi
