cfflush in CF10, Server 2008 R2, and Apache 2.2

I've been googling for a while and I can't find the correct reason for why I cannot get <cfflush> to work.  Any time I use it on my server the output only appears once the page is done loading.  I've tried a small interval and tacking on lots of hidden data to verify it's not the browser.  I'm using Chrome and Firefox with the same results.  Can anyone tell me what I've configured incorrectly or any other additional information?

Thanks in advance,
