Nginx Cheatsheet

Redirects

Permanently redirect from web root to specific URI:

location = / {
    rewrite ^ /sympa/ permanent;
}

Blocks

Stop the POST flood to /autodiscover/autodiscover.xml generated by MS Office/Outlook:

location ~ ^/[aA]uto[dD]iscover/autodiscover.xml$ {
        return 403;
}

Checks

nginx -t checks the configuration and nginx -T shows the complete configuration in the order nginx processes the configuration.
