Host Django on subfolder

My comment doesn’t show the whole picture. When I’ve run Django sites on subfolders, I like to use a dynamic config so that you can still access the machine directly (without the proxy) and have a working web-app. This can help a LOT for debugging tricky stuff like this that is hard to reproduce in dev.

If you do not have the ability to pass the header or modify wsgi.py, you can still set FORCE_SCRIPT_NAME in your Django settings.

3 steps:

1. set up a proxy in front of the webserver that strips the subfolder out of the URL
2. set the X-Script-Name header so that your Django site generates its urls with /myapp/ infront of them — make sure you’re using the {% url %} tag and reverse, vs. hard-coding!
3. modify myapp/wsgi.py to read a new header X-Script-Name into the wsgi environment variable SCRIPT_NAME (based on this flask snippet)

Here is an example Nginx config for a proxy that points to a Django site on a subdirectory and also sets X-Script-Name (steps 1 and 2), note that this doesn’t use a unix socket, so it’s a little different from the OP’s question. Would welcome an edit:

nginx.conf

location /my_app {
    proxy_pass https://mywebapp.com/;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Script-Name /my_app;
    proxy_cookie_path / /my_app;
}

And to read X-Script-Name:

myapp/wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")

_application = get_wsgi_application()


def application(environ, start_response):
    # http://flask.pocoo.org/snippets/35/
    script_name = environ.get('HTTP_X_SCRIPT_NAME', '')
    if script_name:
        environ['SCRIPT_NAME'] = script_name
        path_info = environ['PATH_INFO']
        if path_info.startswith(script_name):
            environ['PATH_INFO'] = path_info[len(script_name):]

    scheme = environ.get('HTTP_X_SCHEME', '')
    if scheme:
        environ['wsgi.url_scheme'] = scheme

    return _application(environ, start_response)
