This is a valid "Fully Qualified Domain Name" or "FQDN" format.
You may also get requests like http://www.example.com:80/lots-of-urls-like-these/ and/or http://www.example.com.:80/lots-of-urls-like-these/
Simple enough to take care of these on most servers... What have you tried so far? Do you intend to put a fix into your .htaccess file, and if so, do you have any other working server config code in it? Does this site use (or plan to use) any other subdomains in addition to the current "www"?
