Removing Slashes from a URL in NGINX

Sometimes you need to remove multiple slashes from an address, for example:

http://mysite.com//page//1.htm/ -> http://mysite.com/page/1.htm

In this case, you can use the following construction to remove slashes from the middle:

set $test_uri $scheme://$host$request_uri;
if ($test_uri != $scheme://$host$uri$is_args$args) {
    rewrite ^ $scheme://$host$uri$is_args$args? permanent;
}

And from the end:

rewrite ^/(.*)/$ /$1 permanent;
