Field Details
-
dwStructSize
public int dwStructSizeSize of this structure, in bytes. This value can be used to help determine the version of the cache system. -
lpszSourceUrlName
Pointer to a null-terminated string that contains the URL name. The string occupies the memory area at the end of this structure. -
lpszLocalFileName
Pointer to a null-terminated string that contains the local file name. The string occupies the memory area at the end of this structure. -
CacheEntryType
public int CacheEntryTypeA bitmask indicating the type of cache entry and its properties.
The cache entry types include: history entries (URLHISTORY_CACHE_ENTRY), cookie entries (COOKIE_CACHE_ENTRY), and normal cached content (NORMAL_CACHE_ENTRY).
This member can be zero or more of the following property flags, and cache type flags listed below.- EDITED_CACHE_ENTRY: Cache entry file that has been edited externally. This cache entry type is exempt from scavenging.
- SPARSE_CACHE_ENTRY: Partial response cache entry.
- STICKY_CACHE_ENTRY: Sticky cache entry that is exempt from
scavenging for the amount of time specified by dwExemptDelta.
The default value set by CommitUrlCacheEntryA and CommitUrlCacheEntryW is one day. - TRACK_OFFLINE_CACHE_ENTRY: Not currently implemented.
- TRACK_ONLINE_CACHE_ENTRY: Not currently implemented.
The following list contains the cache type flags.- COOKIE_CACHE_ENTRY: Cookie cache entry.
- NORMAL_CACHE_ENTRY: Normal cache entry; can be deleted to recover space for new entries.
- URLHISTORY_CACHE_ENTRY: Visited link cache entry.
-
dwUseCount
public int dwUseCountCurrent number of WinInet callers using the cache entry. -
dwHitRate
public int dwHitRateNumber of times the cache entry was retrieved. -
dwSizeLow
public int dwSizeLowLow-order portion of the file size, in bytes. -
dwSizeHigh
public int dwSizeHighHigh-order portion of the file size, in bytes. -
LastModifiedTime
FILETIME structure that contains the last modified time of this URL, in Greenwich mean time format. -
ExpireTime
FILETIME structure that contains the expiration time of this file, in Greenwich mean time format. -
LastAccessTime
FILETIME structure that contains the last accessed time, in Greenwich mean time format. -
LastSyncTime
FILETIME structure that contains the last time the cache was synchronized. -
lpHeaderInfo
Pointer to a buffer that contains the header information. The buffer occupies the memory at the end of this structure. -
dwHeaderInfoSize
public int dwHeaderInfoSizeSize of the lpHeaderInfo buffer, in TCHARs. -
lpszFileExtension
Pointer to a string that contains the file name extension used to retrieve the data as a file. The string occupies the memory area at the end of this structure. -
