asidownloadcache for post request?

In my iOS app,I'm sending a post request using the asihttprequest methods and receiving json data. i want to be able to cache the parsed json data if possible (so that i can dir开发者_StackOverflow社区ectly extract and display in the tableview). asidownloadcache is helpful only if i'm using GET method. So, i'd like to know my options(along with an example if possible) Thanks a ton for the help, in advance..
