Nginx redirect all requests from subdirectory to another subdirectory root

Question

I\'m quite new to Nginx so please bear with me.

I\'m trying to redirect all requests from one subdirectory (store) to the root of another subdirectory (trade). See

You need to ensure that your location ~ \.php$ handler does not take any URLs below the old folder. Indeed, precedence rules are clearly documented within http://nginx.org/r/location, and you can either use regular expressions, or, better yet, use prefix-based matching with the ^~ modifier to instruct that the search must stop without trying to see if that regex-based \.php$ location would match:

    location ^~ /old/long/path/ { # will match /old/long/path/index.php, too
        rewrite  ^/old/long/path/(.*)$  /new/$1  permanent;
    }

The above snippet is likely the most efficient way of doing this, but here is another way of doing the same:

    location ~ /old/long/path/(.*) {
        return  301  /new/$1$is_args$args;
    }

Why does one example has $is_args$args and the other one doesn't? Good question! Note that location directive as well as the first parameter of the rewrite directive both operate based on the contents of the $uri variable, as opposed to $request_uri. Long story short, but $uri does not contain $args, so, in both cases, $1 will not contain any args; however, in the case of rewrite, the case is deemed so common that $args are automatically added back by nginx, unless the new string ends with a ? character, see http://nginx.org/r/rewrite.
