    1. ] cache the pulled news feed as a json object on the server
  2. ] WANT = 
    1. ] if the file has been cached then use the cached file VERSUS pulling the feed again
    2. ] if the file has NOT been cached then pull the feed and create a cached object
    3. ] if the file is > 24 hours old, pull the feed and create
  3. [2013-09-16] i] qry = how to have server automically generate page
    1. ] thinking will need to have the server auto generate and build page using ??? but

    1. ] RESOLVED by yahoo 2013-mm-dd 
  5. [2013-10-04] pseudo code

      2. build page
  6. [2013-10-05][server-side]
