Hi,
We need access to the session from all virtual hosts.
We use cookie-sessions, at the moment url-rewriting isn't a
possible alternative.
Too bad, as that's the only portable alternative.
Till now we solved the problem by specifying the domain globally
in the resin.conf . Yes we used Resin as Servlet-Engine and Resin
supports a config-tag cookie-domain which solved our problem
perfectly. As far as i know Tomcat doesn't support something
like that.
When you use container-specific, non-Servlet-Specification features, you
can expect trouble when trying to move across containers ;)
As I don't have access to the session-cookie,
i thought in creating a cookie with the current session-id and the
proper domain set for every virtual host, but that seems to me
a little bit awkward.
It might be awkward, but if you can't use url-rewriting this might also
be the next best option.
Is it possible to specify a general cookie-domain globally for a
virtual
host?
Not currently.
Is there a way to manipulate the session-cookie (set the domain)?
Not currently.
What is supposed as best practise to get access to one session from
different subdomains?
Use url-rewriting. To enable it, set cookies=false on your Context
declarations.
Any help/comment is greatly appreciated.
Portability is tough to achieve, but great once achieved. Shortcuts and
container-specific goodies end up costing more in the long term, as this
example shows.
