I'm not sure that's what's happening with me, but something worth noting.
Just did some testing, and CF does indeed send an incorrect content-length
value if cflocation is called following cfhtmlhead. And any calls to
cfheader are also ignored if cflocation is used, so you can't even manually
add a "Connection: close" header to help the client determine the end of
the response.
I probably won't have time to dig into this issue any more this week, but
I'll get back to it sometime and if I find a solution, share it with the
list.
