Yes you have. I've used both approaches which pretty much have the pros and 
cons you mentioned.

The browser redirect is:
         self.response().sendRedirect('someURL')

The internal redirect is:
         self.application().forward(self.transaction(), 'someURL')

You can also do an include:
         self.application().includeURL(self.transaction(), 'someURL')

The doc strings in Application.py give info on the behavior diffs of these 
two methods.

In my real projects I have ended up doing both. I'll give 2 examples:

My SignOut.py servlet, which invalidates the user, does a sendRedirect() to 
the front page of my site. I don't want the user to see SignOut in the URL 
after they have signed out. I want them to see the site as if they came to 
it as a new user.

A View.py servlet I wrote can take an "object=" or a "class=" parameter. 
The implementations are sufficiently different that I made a servlet for 
each, ViewObject.py and ViewClass.py, and made View do a forward() to the 
right one. So the user is just aware of "View", but my implementation is 
broken up a little more than that.

I'm sure there are other examples for both and you'll find yourself 
switching between the two depending on what you want.


Hope that helps,
