    • Field Detail

      • dwStructSize

        public int dwStructSize
        Size of this structure, in bytes. This value can be used to help determine the version of the cache system.

      • lpszSourceUrlName

        public Pointer 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

        public Pointer 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 CacheEntryType
        A 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 dwUseCount
        Current number of WinInet callers using the cache entry.

      • dwHitRate

        public int dwHitRate
        Number of times the cache entry was retrieved.

      • dwSizeLow

        public int dwSizeLow
        Low-order portion of the file size, in bytes.

      • dwSizeHigh

        public int dwSizeHigh
        High-order portion of the file size, in bytes.

      • LastModifiedTime

        public WinBase.FILETIME LastModifiedTime
        FILETIME structure that contains the last modified time of this URL, in Greenwich mean time format.

      • ExpireTime

        public WinBase.FILETIME ExpireTime
        FILETIME structure that contains the expiration time of this file, in Greenwich mean time format.

      • LastAccessTime

        public WinBase.FILETIME LastAccessTime
        FILETIME structure that contains the last accessed time, in Greenwich mean time format.

      • LastSyncTime

        public WinBase.FILETIME LastSyncTime
        FILETIME structure that contains the last time the cache was synchronized.

      • lpHeaderInfo

        public Pointer lpHeaderInfo
        Pointer to a buffer that contains the header information. The buffer occupies the memory at the end of this structure.

      • dwHeaderInfoSize

        public int dwHeaderInfoSize
        Size of the lpHeaderInfo buffer, in TCHARs.

      • lpszFileExtension

        public Pointer 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.
