I don't have any info other than what I pasted in. I can fire up
ethereal if it's gonna help, but probably not for a few days at least.
I'm using ieHTTPheaders to get this info.

See below. After the first POST, there was a long delay so I figure the
whole file got sent then. Only after the long delay was I prompted for
username/password. Then comes the next POST (the third one overall, and
the second one with non-zero content length), and another much longer
delay. Looks like 40MB is too big :) and that I caused trouble for the
server. I've pasted the conversation below, and then repeated it again
with a file about 2MB. I may need to get closer to the wire to figure
out what's going on. The first delay (before auth) is way shorter than
the delay after auth. The whole file could be getting transferred and
just dropped on the floor...or at least I could convince myself that
dropping the file is enough faster than writing it to disk to explain
the difference...but I'm just guessing.

I may be able to provide this. I'm looking into it.
