SYMPTOMS
When you write a WinInet application to download files from a server using the HttpOpenRequest function, the file never get cached.



CAUSE
WinInet caches a file in such a way that the cached file is populated as you call the InternetReadFile function. If you don't read the file by calling InternetReadFile, the file is not cached.



STATUS
This behavior is by design.
