GetUrlCacheEntryInfoでインターネット一時ファイルのキャッシュされたアイコンファイル名(favicon.ico)を取得できることが解りました。

  If (GetUrlCacheEntryInfo(lpszUrl, lpCacheEntry, dwEntrySize)) = 0 Then
    If StringFromPointer(lpCacheEntry.lpszLocalFileName) <> "" Then
      GetCacheEntryInfo = True

  StringFromPointer = Space$(lstrlenA(Ptr))
  lstrcpyA StringFromPointer, Ptr
