Upload Progress Issue -- do not have "uploading" state

[Yanxin Z.]

Hello,
I am trying to use Nginx + Upload Module + Upload Progress Module, which
I follow the link
http://wiki.nginx.org/NginxHttpUploadProgressModule#Usage

I find some issue in initial config, like X-Progress-ID should be added
in upload_pass_form_field

Now I have the last problem is upload.state is not changing during file
transfer. When upload starts, the state is "Starting", when upload is
done, state becomes "done". But in the period, states never becomes
"uploading". This cause the status bar is not working.

Could anyone help me to solve this issue?
Thanks.

I post my config here:

247 #            limit_req   zone=box; #set request limit for box
