Hi this seems to be a jetty or GAE bug if you ask me probably causes by
the combination of already rendering something and then causing a
redirect within the rendering (I am not sure if this is even a bug or
maybe some expected behavior),
but try following, since it happens during render time (due to the
getter) try to shift it away from the render time to something in
prerender, you can use following mechanisms to achieve that
a) a servlet filter which issues the redirect
b) a phase listern
c) a system event, for instance a prerender system event
It might resolve this issue.

*Hello Sirs,*

*In my experimental project **http://www.agost.ru*<http://www.agost.ru>* I
use redirection to main page
**http://www.agost.ru/to.do*<http://www.agost.ru/to.do>
* .*
*I have to do it this way because user should obtain session. I use
PrimeFaces to ajax login that does not work without session. *
