in moin.wsgi:

app = make_application(shared=False)

This will let the web server serve the static content like CSS, JS, images.

in moin config (usually

class Config(FarmConfig):
   url_prefix_static = '/path/to/MoinMoin/web/static/htdocs'
location /path/to/MoinMoin/web/static/htdocs {
    alias /path/to/MoinMoin/web/static/htdocs;

location /wiki {
    gzip off;
    include uwsgi_params;
    uwsgi_param SCRIPT_NAME /wiki;
    uwsgi_modifier1 30;
    uwsgi_pass unix:/path/to/uwsgi.socket;

Should be obvious what this is once you’ve seen/done the WSGI configuration and read the ngx_http_uwsgi_module documentation.

Uwsgi also needs --ignore-script-name (or equivalent config file setting) for MoinMoin otherwise it’ll interpret it as a literal path. Moin doesn’t do PATH_INFO very well (or at all).
