  Daily rates

  The daily rates for the date picker are diven by a datafile which exists on the server.
  When a daily rate request is made, the entire month of rates is requested from the server
  and any further requests will be blocked until the data is retrieved.  Daily rate data is
  cached on the client for a total of 10 minutes (configurable) for each client request.
  This allows for the rates to adjust.
