-------------------------+--------------------------------------------------
 The current caching strategy is non-existent.  We should find out which
 HTTP headers are most commonly used to tell clients and proxies how to
 cache our JSON responses.  The caching strategy may rely on information
 that the server has about new data becoming available.

 Arturo says there are two caching approaches: first, the server says how
 long a document will be valid; second, a client may check whether its copy
 of a document is still the most recent document there is.  We should
 probably implement both approaches.

 (This was issue 6 in my GitHub repository.)
