I'd rather not see that much python code in zpt. Frankly,
I prefer to see no Python code in zpt.

Because they aren't the same.  The application url is the url of the entry point
to the Zope server.  A site may have a different URL. The root sites may contain
subsites, for example.

That's odd.

Suit yourself.  Someone should think about why it's happening.

What do you mean by local copied?  wget can adjust absolute urls
for you.
