Thanks for the swift replies, unfortunately I'm still having trouble getting it to play nicely with the upload module.

Here's the config I'm using: http://pastebin.com/GsrYHwj0

It seems as though the request body isn't being read correctly; ngx.req.get_body_data() works as expected if I run it from inside /upload and make a multipart post to it, but it only returns the first line of the body data when run from inside @handler. echo_request_body works fine either way.

Here's what I get when posting to it with the above config:

$ curl -F file=@TDXBN.gif http://localhost/upload * post defs: content_type: multipart/form-data; boundary=----------------------------ff78acc43147 maxinput: 2097152 content_length: 358 maxfilesize: 1048576 args:

* post args:

* request body: ------------------------------ff78acc43147

On a slightly different tack, I noticed one of the release announcements for ngx_echo showed this directive being used:

echo_subrequest PUT /some_upstream/$upload_file_md5 -f $upload_tmp_path

Is there something in particular you need to do to get access to $upload_tmp_path etc. outside of the upload_set_form_field directive? I've tried hacking this into working with echo_subrequest, but if i try to use any of the $upload_* variables anywhere outside of that directive then it doesn't work at all.
