The IdP didn't approach it that way, but it might have made more sense to do that.</p> <p style="margin: 10px 0 0 0">With the SP it's much more useful to abstract it that way because the session cache code itself is so terrible. We may need to add some hooks there to expose serialized sessions and inject them for deserialization but that's largely outside of the flow of the current code so less risky to do.</p> <p style="margin: 10px 0 0 0">Meanwhile..</p> <p style="margin: 10px 0 0 0">Saving the session state for use is something that can be done cleanly via a sessionHook routing to a Handler that handles this. It could be done relatively brute force by generating a full packet and trying local storage and if that fails falling back to generating a smaller packet into a cookie. It's one round trip but extra work to serialize and secure data. Local storage is pretty universal though, so I doubt the extra work would happen much.</p> <p style="margin: 10px 0 0 0">Recovery is harder, but if we approach this as a SSO protocol, that immediately raises the possibility of implementing the bulk of it in a SessionInitiator plugin that could be injected at the beginning of the chain since it essentially short-circuits the use of the traditional ones.</p> <p style="margin: 10px 0 0 0">There are some subtleties there because of passive content rules that normally wouldn't cause the chain to run so probably means changes to the SessionInitiator interface and to the logic that does session lookup and handles passive rules.</p> </td>
