As of version 2.2.1 the web server supports the bytes ranges http header and virtual hosts. The first is required by the new scheme used by the GR warnings programs. The virtual host support now makes it possible to use url's like

    http://warnings.opennoaaport.net:8016

instead of

    http://www.opennoaaport.net:8016/digatmos/warnings

The file dist/httpd-vhost.conf-ex in the Npemwin configuration directory has explanations and examples of the virtual host configuration syntax and options.
