Eelco Dolstra	66a3ac6a56	Allow a binary cache to declare that it doesn't support "nix-env -qas" ... Querying all substitutable paths via "nix-env -qas" is potentially hard on a server, since it involves sending thousands of HEAD requests. So a binary cache must now have a meta-info file named "nix-cache-info" that specifies whether the server wants this. It also specifies the store prefix so that we don't send useless queries to a binary cache for a different store prefix.	2012-07-27 18:16:05 -04:00
