anything else. This will make (lib)curl to consider the connection connected

4.18 file:// URLs containing drive letters (Windows, NetWare)
When using cURL to try to download a local file, one might use a URL
in this format:
file://D:/blah.txt
You'll find that even if D:\blah.txt does exist, cURL returns a 'file
not found' error.
According to RFC 1738 (http://www.faqs.org/rfcs/rfc1738.html),
file:// URLs must contain a host component, but it is ignored by
most implementations. In the above example, 'D:' is treated as the
host component, and is taken away. Thus, cURL tries to open '/blah.txt'.
If your system is installed to drive C:, that will resolve to 'C:\blah.txt',
and if that doesn't exist you will get the not found error.
To fix this problem, use file:// URLs with *three* leading slashes:
file:///D:/blah.txt
Alternatively, if it makes more sense, specify 'localhost' as the host
component:
file://localhost/D:/blah.txt
In either case, cURL should now be looking for the correct file.
