On the documentation I have found: "shared - Whether or not multiple bindings (different sites/context roots) are to be shared. Sharing implies sharing of sessions, servlet instances etc. The default is 'false'." But I would like to know how this works. Where could I specify which context have to share its contexts? Is it possible to share a SSL context and a non-secure one ? Have any of you tried this? Regards, Ismael Blesa
