    ~: If a tilde modifier is present, this location will be interpreted as a case-sensitive regular expression match.

    ~*: If a tilde and asterisk modifier is used, the location block will be interpreted as a case-insensitive regular expression match.

  2. cduffin is correct.

    Here is an example of using this regex for a location block to reject uri's that try to access a certain file type (assuming we are using try_files lower in the nginx config)

    location ~* \.(txt|log|config)$ {
    return 403;
}
