Retrieves information on the cache entry associated with the specified URL, taking into account any redirections that are applied in offline mode by the HttpSendRequest function.

Syntax

BOOLAPI GetUrlCacheEntryInfoEx(
  __in         LPCTSTR lpszUrl,
  __inout_opt  LPINTERNET_CACHE_ENTRY_INFO lpCacheEntryInfo,
  __inout_opt  LPDWORD lpcbCacheEntryInfo,
  __reserved   LPTSTR lpszRedirectUrl,
  __reserved   LPDWORD lpcbRedirectUrl,
  __reserved   LPVOID lpReserved,
  __in         DWORD dwFlags
);

Parameters

lpszUrl [in]

Pointer to a null-terminated string that contains the name of the cache entry. The name string should not contain any escape characters.

lpCacheEntryInfo [in, out, optional]

Pointer to an INTERNET_CACHE_ENTRY_INFO structure that receives information about the cache entry.

lpcbCacheEntryInfo [in, out, optional]

Pointer to a variable that specifies the size of the lpCacheEntryInfo buffer, in bytes. When the function returns, the variable contains the number of bytes copied to the buffer, or the required size of the buffer in bytes.

lpszRedirectUrl [out]

This parameter is reserved and must be NULL.

lpcbRedirectUrl [in, out]

This parameter is reserved and must be NULL.

lpReserved

This parameter is reserved and must be NULL.

dwFlags [in]

This parameter is reserved and must be 0.

Return Value

Returns TRUE if the URL was located, or FALSE otherwise. Call GetLastError for specific error information. Possible errors include the following.

Remarks

GetUrlCacheEntryInfo does not do any URL parsing, so a URL containing an anchor (#) will not be found in the cache, even if the resource is cached. For example, if the URL http://example.com/example.htm#sample is passed, the function returns ERROR_FILE_NOT_FOUND even if http://example.com/example.htm is in the cache.
