Nginx and Gunicorn WSGI Variables

I'm testing Gunicorn as an alternative to uWSGI. An Nginx reverse-proxy is set up in front of the Gunicorn instance. A consequence of not using uWSGI is I have to resort to using Nginx's proxy_pass instead of uwsgi_pass. With uwsgi_pass I could use uwsgi_param to overwrite the PATH_INFO and SCRIPT_NAME WSGI variables. proxy_pass has no equivalent directive. How do you set these WSGI variables for proxy_pass for a WSGI compliant application server such as Gunicorn?

The Gunicorn documentation suggests that you can specify SCRIPT_NAME through an HTTP header without any further explanation. Digging through the source code revealed that it accepts a non-standard header actually named SCRIPT_NAME. The following can be used to set SCRIPT_NAME for Gunicorn:

proxy_set_header SCRIPT_NAME /myapp;

PATH_INFO cannot be set. However, in my case PATH_INFO does not need to be set for Gunicorn because it automatically strips the SCRIPT_NAME prefix from PATH_INFO. With uWSGI I had to overwrite PATH_INFO to strip the SCRIPT_NAME prefix.
