If you can see this, it means that the installation of the Apache web server software on this system was successful. You may now add content to this directory and replace this page.
The empty string in the hostname position denotes localhost. So you have the same as http://localhost. The linkness of your link is syntactically present and referent-ly observer-dependent.
This is an invocation of authority. The URL in the grandparent post does not match the grammar specified in RFC 1738, and none of the browsers I have on hand to test with will follow it. Which browser sent you to localhost?
1738 is insufficiently formal, and AFAIK is superseded by 2616 and 3986. 3986 (URI Generic Syntax) says that the host component is required, but one of the alternatives for it is “reg-name” which may be zero-length, but:
If the URI scheme defines a default for host, then that default applies when the host subcomponent is undefined or when the registered name is empty (zero length). For example, the “file” URI scheme is defined so that no authority, an empty host, and “localhost” all mean the end-user’s machine, whereas the “http” scheme considers a missing authority or empty host invalid.
RFC 2616 (HTTP/1.1) specifies the host as being non-optional and using the grammar from RFC 2396, which defines it such that the empty string is not included. Therefore my previous claim was incorrect per specifications.
Safari 4.0.4 Mac implements http:// and http:///foo as equivalent to http://localhost/ and http://localhost/foo/, possibly by analogy to file:///foo/.
This is not a pipe.
This is not a link.
Are you sure about that?

FWIW, chrome opens an “about:blank” tab, not localhost.
This is twice the not a pipe.
[http://x This is not a link].
[http://]
[http:// This is not a link].
Cool. Surprised no one has painted an infinitely recursive version yet.
Tried, but got a stackoverflow, and stackoverflow didn’t help to solve it.
