Syntax

typedef struct _HTTP_CACHE_POLICY {
  HTTP_CACHE_POLICY_TYPE Policy;
  ULONG                  SecondsToLive;
}HTTP_CACHE_POLICY, *PHTTP_CACHE_POLICY;

Members

Value	Meaning
HttpCachePolicyNocache	Do not cache the data at all.
HttpCachePolicyUserInvalidates	Cache the data until the application explicitly releases it.
HttpCachePolicyTimeToLive	Cache the data for a number of seconds specified by the SecondsToLive member.
