I fell into the same trap, linking map files to individual pages by
specifying their key in the metadata. It fails terribly because the
browser won't understand the directory structure. For example, you might
surf to "freenet:CHK@blahblah", a html page, which links to a map file in
its metadata. But that key might not really be in the top directory ("/"),
but it could be listed in the mapfile as "/chapter_01/index.html". This
introduces a whole slew of evil complications, because the browser lies
about the filename it's requesting. There's no way out, you're stuck
trying to keep track of your current state (what directory you're in) with
cookies, and even then it falls apart. A link off /chapter_01/index.html
to "../cat.jpg" would do what when the browser thinks "/chapter_01/"
equals "/"? My brain still hurts.
By explicitly specifying the map file and absolute filename in the URI, we
sidestep these difficulties. Practically speaking, this means that the
user will have to surf to "freenet:KSK@mysite:/index.html" instead of
"freenet:KSK@my-sites-index-page-with-the-map-specified-in-metadata".
