[C2] How can I set "default" session attributes?

["Gapinski, Gary (GEL, MSX)" <Ga...@lighting.ge.com>]

I wish to create a sub-sitemap in which all requests are preceded by a
conditional setting
of some session attributes. In particular, I would like to set an attribute
specifying a database
connection pool identifier (to be used by default until a specific request
is later received to change it).
As well, I would like to establish a default locale and timezone for the
session to be used for
subsequent requests (again, if/until a request to change either is
received).
Once I can guarantee that such attributes are available as session
attributes, I would use the
session logicsheet to obtain and use these values within generation steps.

I have not been able to puzzle out how this might be done.

I have looked at SessionPropagatorAction as both an individual action as
well as part of an action-set,
but I have been stumped trying to determine how to have such an action take
place in the presence
or absence of a pre-established session, nor have I found how to get the
attribute(s) set regardless
of which of several matchers handle the request (I'd like any matched
request to undergo the same
setting of default attributes).

Should I be looking at actions, action-sets, selectors, or other techniques?

Regards,

Gary

Hi Gary,

If you look at the "protected" examples available from the C2 welcome page
($TOMCAT_HOME/webapps/cocoon/protected) you will see an example of where
session validation is done through actions and a "params.xml" file is used
to set the session vars, including defaults.
