[Zope] Generating non-existent documents on the fly?

[Stefan Hoffmeister]

Is there a way to generate non-existent documents on the fly - some kind
of "rewriting" the target URL?

Example site structure

  /root (http://localhost/)
     /content
        layout_template
        some_txt

A user queries

  http://localhost/content/some.html

Obviously, "some.html" does not exist. This is where some mechanism (the
one I am trying to find <g>) kicks in. It will analyze the query string,
detect that there is "some_txt" and "layout_template". Based on that it
will generate "some.html" on the fly.

Any ideas?

I'd rather not want to have question marks in the query; my attempts to
play with standard_error_handler unfortunately did not yield anything.

Thanks!
