This has been discussed before, but is not currently supported out of the
box. Terrel was the big champion here. See:
http://www.ics.uci.edu/~tshumway/webware/
and more specifically:
http://www.ics.uci.edu/~tshumway/webware/urldecode.html
Obviously, you'll have to do some serious work to get this happening.

You should be able to use request.uri().

I just make the URI like so:
self.sendRedirect("SomeoneElse?x=%i&y=%i" % (x, y))
You can also make use of request.adapterName() if you have some reason to.

The only approaches I use and recommend (in no particular order):
* Make an abstract FooPage class from which the two classes descend.
* Make a mix-in class. This is very similar to the one just above, but the
point is that the mix-in is not part of the primary inheritance tree of
your pages and can be used here and there as you need it. It adds methods
where methods are needed.
* Make an independent Py module featuring functions or "global" data.
Perhaps the data is initialized only once when the module is imported. This
is can be nice because importing modules is threadsafe in Python.
* Use composition. e.g., import a class from a shared module and create an
instance which your servlet keeps around and uses.
Well, that's all that comes to mind. I've been happy with and have used all
4 techniques.
