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

[Jingyi Wei]

Hello Nils,

Thanks for your email. I think the difficulty of the return(refresh)
approach might be: VRY_Finish(req, DISCARD) will run instead of
VRY_Finish(req, KEEP) in cnt_lookup(), and do not fetch again if there
is already a busy object after VCL_hit_method().

Thanks,
Jingyi
