www.widget.com
www.widget.com/
Which one is right and what's the difference? (please)
You talking about URLs published on the WWW? If so then both are
wrong, unless they're meant to be resolved as relative URLs[1]
If you meant
http://www.widget.com versus
http://www.widget.com/ then
both are correct. The "/" which separates the host part of the URL
from the local part of the URL is optional when the local part is
empty.
Don't confuse that with the trailing slash on, let's say,
http://foo.example/bar versus
http://foo.example/bar/
Those are two distinct URLs, either or both of which *could* refer to
distinct resource(s) at the server. Which one(s) are correct depends
on your server configuration.
What did you *really* want to know? If you're referring to the sloppy
habit of typing incomplete URLs into your browser's URL bar, then the
rules are whatever the browser developer has implemented, since *that*
would be of purely local significance.
have fun
[1] in which case they'd be resolved relative to the absolute URL of
the page which referenced them, let's say
http://www.foo.example/some/path/to/www.widget.com , with or
without a trailing slash.
