Other web frameworks allow you to customise the name of the session
cookie to avoid this sort of problem where different applications run
on different ports under same host name. Other web frameworks also
allow one to cleanly mount multiple instances of an application under
different sub URLs of same host/port and where they need different
session contexts, allow you to have the session cookie path be the sub
URL so they are distinct for each instance.

If web2py can't do this, it is a design/implementation limitation, not
a feature.
