I suggest considering tools like the Apache module mod_rewrite to allow an indipendence of URIs from implementation choices. URIs should not change if you switch from a single script to a multiple script approach and they should be more related to contents than to application paths.

Thus, a preliminary step should take care of converting http://www.mydomain.org/posts/insert.html to either app.cgi?mode=edit or edit.cgi.
