Hmm... In my testing I saw requests with If-Modified-Since: and 
If-None-Match: headers being sent and a 304 Not Modified response being 
sent.

I added INTERNET_FLAG_RESYNCHRONIZE, which looks like it might be needed 
to do the right thing if the server doesn't send an ETag header, and 
made another build.

Perhaps you could try that and see if it improves things?
