I'm pretty sure IE uses a completely different set of calls for it's
XHR, so maybe you need to research if there is something tricky that
we are missing.

Anyway, I'm trying to debug why the profiler is acting weird in
DHTML in IE7. I don't get any errors from the
IE script debugger, and boy is it ever slow, but when the profiler
output is analyzed, there's just some stuff that
seems to have gone missing.
I tried an experiment to see what would happen in the profiler if I
set the XMLHTTPRequest.open() call to use
synchronous instead of asynchronous return.
In Firefox on the Mac, the 'chunks' of profiler data from the client
to the server go up in a seemingly random order, closer to the
reverse order of how they are called,
based on the 'seqnum' field. E.g., I see seqnum 10,9,6,5,4,8,7,3,2,1
or something like that. It's the opposite of what I'd expect. I even
tried setting the Firefox max net connections to
one. Maybe internally the browser doesn't send requests in order
that they are queued. The server reassmbles the into the correct
order so it shouldn't matter anyway, but it still gives bogus
results from IE7. I guess I'll try smaller example case and see if I
can
find some problem there.
