Как составить Rewrite начинающийся с точки nginx?

server {

listen 80; ## listen for ipv4

server_name test.pro www.test.pro;
set $main_host 'test.pro';

#Делаем, чтобы сайт не открывался по IP
if ($http_host ~ "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}") {
return 444;
}

if ($host != $main_host) {
rewrite ^(.*)$ http://$main_host$1 permanent;
break;
}

root /var/www/$main_host/www;
index index.php;

## Disable viewing .htaccess & .htpassword
location ~ /\.ht {
deny all;
}

if ($http_user_agent ~* "WordPress") {
return 444;
}

location / {
try_files $uri $uri/ /index.php?$args;
rewrite ^/(.+?)/(.+?)$ /cp.php?name=$1&nick=$2 last;
}

location ^~ /.well-known/acme-challenge {
default_type "text/plain";
}

location ~ \.php$ {
fastcgi_pass 127.0.0.1:9056;
include /etc/nginx/conf/fastcgi_params.conf;

fastcgi_param SCRIPT_FILENAME /var/www/$main_host/www$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT /var/www/$main_host/www;

fastcgi_param PHP_ADMIN_VALUE upload_tmp_dir=/var/www/$main_host/tmp/upload;
fastcgi_param PHP_ADMIN_VALUE session.save_path=/var/www/$main_host/tmp/sessions;
