Answer 1

Your existing location ~ \\.php$ block serves the /usr/share/nginx/html/default root. You need a nested location to process PHP files under the /calendar URI.

Assuming that your calendar app is designed to work within a subfolder, this may work for you:

location ^~ /calendar {
    alias /usr/share/nginx/html/calendar/davical/htdocs;
    index index.php;

    if (!-e $request_filename) {
        rewrite ^ /calendar/index.php last;
    }

    location ~ \.php$ {
        if (!-f $request_filename) { return 404; }

        include        fastcgi_params;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_param  SCRIPT_FILENAME $request_filename;
    }
}

Use the ^~ modifier to prevent the other location ~ \\.php$ block from taking precedence (see this document for more). Use $request_filename , as it works with alias . Avoid using try_files with alias (see this issue ).
