Hi all

I've noticed that some websites use absolute paths when linking to local
files, e.g. '/', '/style.css, '/images/logos/header.gif' etc., which has
the advantage that pages in subdirectories can use the same paths as
pages in the root, but also has the disadvantage that the site has to be
developed in the root folder (htdocs) rather than a subdirectory
(htdocs/myproject).

And some sites use relative paths ('images/logos/header.gif' or
'../images/logos/header.gif' if the page is in a subdirectory of the
root) which has the advantage that the site can be put in any directory
and the paths will work, but the disadvantage that calling functions
that create HTML or including chunks of HTML can be a problem because
the paths will need to change depending on the directory of the page
using the HTML.

Other sites seem to use a combination -- linking relatively to some
files but absolutely to others.

I'm never really sure which route to take. Are there reasons for
choosing absolute or relative paths that I'm not aware of?
