Hi,

Thank you for you reply.

I tried this method. Under Firefox, it works great. Every time the
server script calls flush(), the callback function of Ajax request
will be called with readyState set to 3. So I can update the progress
with the responseText variable. But unfortunately, this doesn't work
in IE. In IE, the callback will only be called only once with
readyState set to 3.

I hate IE!!
