Hi, I'm running nginx as a reverse proxy for an Apache/mod_perl application, and have a fancy-upload progress bar that measures the amount of content uploaded. If the script doesn't see any progress after several seconds, the client-side JavaScript assumes the upload has failed for some reason and restarts the upload.

However, now that I have nginx running in front of Apache, it seems to be buffering the uploaded content and isn't sending any of it to Apache until the upload finishes (or at least until the upload progresses long enough for the client-side to give up and retry). Is there any way I can tell nginx to stop buffering and simply send all the content to Apache as it recieves it? I only am using nginx for SSL and serving static files, so I don't want it to do anything special to my dynamic URIs.

Can anyone help me out with this, or tell me if there's a way my Apache application can detect the upload in-progress within nginx? As long as I can watch the upload progress I can be happy, but my application needs to be made aware of the upload.

Thank you
