To be honest I'm not sure how you are getting this right, its probably best to use separate namespaces though, then you can use URL rewriting to make them appear as one, this solution is really powerfull, we use it to integrate all our apps in our domain, we even integrate Java and Perl apps using Apache mod_rewrite, there is a similar module for tomcat called tuckey http://tuckey.org/urlrewrite/

Subject: Suggestions for overlapping URI spaces

All,
I have two applications deployed in production that share a URL space.
Actually, one is deployed as the root webapp, the the other one is at,
say, "/foo".
My problem is that each webapp maintains its own session identifiers as
cookies. Since the session id cookie is always called JSESSIONID, a
visitor who uses both applications gets two cookies (one with /, and one
with /foo) with different JSESSIONID values. I'm guessing that Tomcat
doesn't try to pick the "best" one, since things get /really/ confusing
when this happens. Basically, our users get caught in a continuous
please-login -> login -> please-login -> login loop. It appears that the
root JSESSIONID is being preferred over the more recent /foo one, which
is never read properly so the login can never happen.
Does anyone have any suggestions for how to fix this? Some obvious ideas
are:
1. Don't do that.
2. Change the session id cookie name in one of the apps (is this
possible and/or recommended?)
3. Use SSO -- except that I currently deploy these two applications
in separate Tomcat instances.
4. Re-deploy the root webapp to /bar and forward / to /bar.
I'm just looking for the "right" solution. Any comments or suggestions
would be appreciated.
Thanks,
- -chris
