Has anyone set up nginx to work with an AJAX uploader like this one  
before? [http://valums.com/ajax-upload/](http://valums.com/ajax-upload/)

Passing the upload through to my Tornado server works fine, but I want  
nginx to handle the file before it gets that far. I have nginx set up  
to intercept regular file posts from our pre-AJAX page with  
“upload\_pass” and “upload\_store,” but now with the file in the body of  
an XHR request, nginx doesn’t treat it as a file for things like  
“upload\_store.”

Also, my AJAX page gets back a 415 error when trying to send the file.  
I’m using the script for image uploads if that makes a difference.

I was thinking I might be able to save a log of the request as the image  
file, but that seems like too much of a hack.

Any help appreciated,  
Zach
