It's a quirk in what constitutes a well-formed file URL.  There are
three distinct forms (at least) that will be picked up as a file by at
least some browsers (and probably by urlgrabber).  In at least galeon:


all resolve to the local file at /path/to/file.  Galeon, at least,
rewrites this as the first, "properly formed" URL in the actual current
location and history. What won't work is:




So it is entirely possible that


would work as well, with no file: at all, although I haven't tried it.

The point is, of course, that the file component of a URL does not
inherit an implict "head" of /. (a root path), while a web or ftp
component does inherit the root path of the website, or rather, the
primary web address is a representation of the root path.

I made the observation in the article because I am aware of at least two
people who tried the file:// form by accident, probably because it
"looks like" http:// or ftp://.  I personally am not religious about the
formedness of URL's, but find it easy to get into trouble with leading
"/"'s and the kind of site you reach if you get in the habit of leaving
off http://, ftp://, file://.  Hence my endorsement of the latter form,
with leading /.
