CSI Web Server
Backfill – The interval, in seconds, for the backfill (e.g., 3600
would be 1 hour).
Format The Format is the format in which to return the data. Options
are HTML, JSON, TOA5, TOB1, XML.
If a value of json is specified for the format parameter and the
web server has a large data set to send, the web server may
choose to break the data into multiple requests by specifying a
value of true for the more flag in the JSON output. If this flag is
set to true, the user will need to send another request to get the
additional data. NOTE
