Yes, but if a page is http://project.example.com/index.html, having a =
relative URL like '../images/foo.jpg' doesn't do you any good, as =
allthough it may seem a valid path on the server, a browser doesn't =
request relative urls from the server, it translates them and uses a ful=
ly =
qualified url. In the example, there is no path above =
http://project.example.com... Would you have had =
http://www.example.com/foo/bar.html, with a src attribute like =
'../images/foz.jpg', the browser requests =
'http://www.example.com/images/foz.jpg', NOT '../images/foz.jpg'.

example.com is reserved for those purposes. Here, from s browsers point =

view, there is clearly no path above it.

Nope, you can't go outside the root folder (you can offcourse serve file=
s =
outside the root folder using some scripts on the server, that's beside =
=
the point though), the browser MUST have a 'reachable' destination. The =
=
browser doesn't know lick about your filesystem, and can't examine it. =
Having the path 'http://www.example.com/', there's no logical way a =
browser can select a directory above that, or even guess at how to acces=
s =
it.
