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

[Dridi Boukelmoune]

Hi Nils,

It's actually return(fetch) that will do that from vcl_hit. You can
see it in the built-in VCL[1] and I'm afraid it hasn't been documented
yet in the 4.0[2] branch, ironically it is documented but deprecated
in the trunk[3].

Cheers,
Dridi
