Specifies the HTTP Cache-Control general message header directives.
property CacheControl: String;
CacheControl is a String property that contains HTTP Cache-Control general message header directives in an HTTP request or response. CacheControl indicates the behavior that prevents a cache from adversely interfering with the request or response, and generally override the default caching algorithms.
Cache directives are unidirectional, and the presence of a directive in a HTTP request does not imply that the same directive will appear in a HTTP response.
Some common values for CacheControl in a HTTP request include the following:
'no-cache' |
'no-store' |
'max-age=' [delta-seconds] |
'max-stale=' [delta-seconds] |
'min-fresh=' [delta-seconds] |
'no-transform' |
'only-if-cached' |
Some common values for CacheControl in a HTTP response include the following:
'public' |
'private' |
'no-cache' |
'no-store' |
'no-transform' |
'must-revalidate' |
'proxy-revalidate' |
'max-age=' [delta-seconds] |
's-maxage=' [delta-seconds] |
CacheControl is not normally implemented for HTTP/1.0, which might |
contain a header value for storage in the the Pragma property that |
contains the value 'no-cache'. |
