Hi everybody,
I have a problem with the cache module. On the Public instance of Magnolia,
when I have a jsp page which takes more than 9 - 10 seconds to load, I get the
following exception:
[code]

In the Author instance I don't get this problem: in effect the Cache module
configuration is set differently in the author and public instances. These are
the cache configuration differences:
Public Instance:
- info.magnolia.module.cache.cachepolicy.Never
- info.magnolia.module.cache.browsercachepolicy.Never
Author Instance:
- info.magnolia.module.cache.cachepolicy.Default
- info.magnolia.module.cache.browsercachepolicy.BrowserCachePolicySet
I've tried to change the Public configuration with the Author ones and I solved
the problem described in the exception, but then raised strange behaviors: I
have a private part in the website where users have to login. It happens that I
couldn't log out from users logged in sessions. It seems like the cache module
takes in memory some user sessions and other users that try to login after,
enters with the previous user credentials.
Any ideas?
Additional info:
- Magnolia Community Edition 4.4.6
- Application Server Tomcat 6
Thanks in advance!
Fabio
