Note, that "http://bar/percent_s" is not set through HTTP (unless you
are talking through proxy, but that is a different use case).

It just connects to "bar" and sends
GET /percent_s HTTP/1.1

Well, HTTP/1.1 added the Host header.

If you need http://foo/ to be sent to server bar, configure your DNS
(e.g. by editing /etc/hosts) so that "foo" resolves to bar's IP

Regarding user:passwd_at_host syntax it us up to browser how to interpret the URL.
If browser cannot interpret username and password in the URL it is
just browser's thing.

I remember hearing 3 or more years ago that the commonly used web
browsers at that time were just silently swallowing the username and
password part before host name, and somebody used that for spoofing
http addresses.

Quick googling - it is year 2002 Mozilla bug:

See URL field and comment #2 in that bug report for an example.
