The "//user:password@host:port/path" notation is defined as "Common
Internet Scheme Syntax" in secion 3.1 of RFC 1738. This section does not
specify that the "http" URL schema follows this syntax, merely:

> The scheme specific

Secion 3.3 "HTTP" says that the syntax for the http schema is

    http://<host>:<port>/<path>?<searchpart>

and further states:

> No user name or password is allowed.

D'oh!

So if you are a "producer" of http URLs, you would be breaking RFC 1738
if you put the "username:password@" in a http URL. But I suppose you
could be more lenient as a "parser" of URLs. Allowing a super-set of the
http schema defined by RFC 1738 may still mean you are a valid 1738
parser...

In any case, I definitely find the "username:password@" syntax useful!
