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

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.

u

public Wininet.INTERNET_CACHE_ENTRY_INFO.UNION u

A union of the last two distinct fields in INTERNET_CACHE_ENTRY_INFO

additional

public byte[] additional
