Hello,

I recently installed [NGINX Upload Progress Module | NGINX](http://wiki.nginx.org/HttpUploadProgressModule)  
with nginx 1.2.6.

On the client side I have a request coming every second to check on  
the upload status. As I watch the access.log I can see all of the  
status check requests before the actual file post shows up in the  
access log.

I am wondering if that is normal or should I see the file post show up  
in the access log then the status check requests after that?

It’s normal. Logging happens after a request processing is  
complete, after sending the response, and hence status check  
requests are logged before the file post.

Hi!

If you compile your nginx with debug - enable debug logging, restart  
nginx  
and you will see messages from upload module, it is very helpful.

Also read this note  
[NGINX Upload Progress Module | NGINX](http://wiki.nginx.org/HttpUploadProgressModule#track_uploads) - “The POST  
\*  
must\* have a query parameter called \*X-Progress-ID”… \*If the POST has  
no  
such information, the upload will not be tracked…

I have double checked and I can see the post variable X-Progress-ID  
coming with the upload but the status just stays at starting. My  
nginx.conf looks like this:

worker\_connections 1024;

1. It must be not a “post variable” - it must be query variable.

For example:

\<input type="file" ...
1. Did you try enable debug? What you have in logs related to  
uploadprogress module?

I am curious. The status never gets past “starting” in the progress  
response. Where should I look to try to debug this? I am not very good  
at system admin.
