Dear Laurie,
thanks for your quick response, maybe I would rename this thread as: Does
Struts 2 support clustering? (see
link<http://mail-archives.apache.org/mod_mbox/struts-user/200804.mbox/[EMAIL
PROTECTED]>
)
I have doubts about the replicacion of a SessionMap object on the quoted
architecture, What do you think?
Regards
