Q:

Change URL in Nginx Config

How can I change url to go to only one location rather than request coming from.
URL : 

www.example.com/blog is going to /var/www/blog (which is correct)
www.example.com/blog/abc should go to /var/www/blog instead of /var/www/blog/abc 
location /blog {
  alias /var/www/blog;
  location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }
}

A:

The SO 30 characters minimum rule is ridiculous.
rewrite ^/blog/abc$ /blog;
