Below is the beginnings of something I hope will grow into an example of
URL/internalPath/pretty urls creation in wt. This is crucial for me (and
others I'm sure) to understand to get SEO aspects correct in future
developments. In an attempt to understand this better I have come up
with the following code which I submit for review (be as harsh as you
like :) ) As i said it's very rough and I guess I'm feeling it out to
see if I have the general concept right and if this can evolve into a
useful example.
One thing I would like to ask is when pathChange is called it appears to
be called for each component of the path (a component being a string
following a "/") in turn. How do I determine which is the final path,
that is, pathChange will not be called again?
Anyway, here it is, any and all input is gratefully acknowledged.
