[web2py] how to show multiple controller's views on the same page?

[ivytony]

I'm a newb to web2py and have been reading the Web2py book freely
online. I am wondering whether it is possible to show multiple
controller's views on the same page (say index page), the reason I'm
asking this is I can only have one view for each controller (e.g.
http://localhost/web2py/app/controller1/view1.html), but what if I
want to show different controllers' output on the index page? can I do
this by including their views in the index view page?
