Cache screwed me up

My co-worker wrote a C++ function that uses the CInternetfile class to get a file via FTP from our server to a local directory, say C:\XXX.  However, we found out, after installing IE5, the file is cached in the Temporary Internet Files Directory.  Therefore, sometimes when I open the file from C:\XXX, the content is the same even if the content on the server has changed.  It obviously got the file from the cache.  
I tired to delete the file from the cahce, but windows does not allow me to do so sometimes.  From Visual Foxpro, I can't delete the file from the cache too.  I believe that it is controlled by Windows.  so I guess deleting the file is not a possible way...

How can I force it to download from the server, not the cache?

1. There is an option which controls the behavior.

Control Panel/Internet/General/Temporary Internet files/Settings/Check for newer versions of stored pages

2. Use the Persistent URL Cache Functions to delete the cached files, such as DeleteUrlCacheEntry.
