URLs of the form ht tp://foo@b ar. com are really just ht tp://b ar. com, with 'foo' as a login username. Note that it's not /possible/ to 3xx redirect this, as the browser will only send the username 'foo' if the server returns a 401 not authorized status to an anonymous request - and only after the user is then prompted for a password as well, usually.
The general syntax is this:
You can also see this technique used in some phishing emails - they'll use things like ht tp://www .paypal .com[lots of spaces]@www .somehackedserver. kr/cgi-bin/owned.pl
[spaces inserted in URLs to avoid your linkspamfilter, feel free to edit them out]
