What is the meaning of the tilde after the location block in the nginx configuration?

for example 

location ~ ^/download/(.*)$ {
  alias /home/website/files/$1;
}

What is the difference between with and without the "~" ?

  • A google search for "nginx tilde" gives the answer as the first result... Basic Nginx Configuration – Linode Library https://library.linode.com/web-servers/nginx/configuration/basic‎ Jul 26, 2013 - When a location directive is followed by a tilde (~), nginx performs a regular expression match. These matches are always case-sensitive. – Drew Khoury Mar 12 '14 at 09:34

The tilde instructs nginx to perform a case-sensitive regular expression match, instead of a straight string comparison.

More details in the docs.

    Additionally, ~* modifier for case-insensitive reg exp matching and ^~ modifier to override possible matches elsewhere. – Akseli Palén Nov 20 '20 at 18:51
