Neither. That's HTTP. Specifically, basic auth.

While this can be done in your server side programming language (e.g. in PHP and a Perl module), it is usually handled by your web server. The specifics depend, of course, on which web server you are using. For example, here are instructions for Apache HTTPD and for IIS.
