Multiple variables in kraken/channels

So there is no way to get one API request like api.twitch.tv/kraken/channels?name=a,b,c,d

  1. The other idea is to get ~50 json request:
    api.twtich.tv/kraken/channel/a
    api.twtich.tv/kraken/channel/b
    api.twtich.tv/kraken/channel/c

save it to one .json file on server and read from that json. but is hard to realize that thing.

  1. what do you mean by caching channel objects? some example?
