Fields

Default	0	Always use the cache algorithm specified in RFC 2616 by the IETF to optimize network bandwidth.
MostRecent	1	Use the local HTTP cache if possible but always ask the server if more recent content is available. The server returns an HTTP status code of 200 (OK) or 304 (Not Modified) when the local content is the most recent.
NoCache	3	Do not use cache nor do a conditional request. This ensures that all HTTP requests go directly to the server.
OnlyFromCache	2	Only use data from the local HTTP cache. This is the offline behavior.
