Re: [Engine-devel] REST session management

Hi Oved, +1 for this feature. [[As a background to the others on the list, this feature is absolutely essential for certain types of ISV integration. Many ISVs need to mirror the RHEV inventory (i.e. all VMs, clusters, basically any object managed by RHEV) in realtime to their own database. The way they do this currently is by polling /api/events and look for changes. In order to be able to react to changes fast, they typically poll every 5 seconds. The query itself is very efficient, so it doesn't cause a whole lot of load on RHEV-M. But it floods the log with login/logout events. This persistent session feature is a solution for that.]] Actually my vote would go for your variation #2: The client passes the "Prefer" header field on every request, besides the last one. When the server gets a request with a JSESSIONID, and without the "Prefer" header, it logs out the session. It's mostly my gut feeling, but i would say it has these advantages: 1. It is more explicit, as on every request you confirm that you still want the authenticated session to be maintained. 2. It is also consistent with the default we have chosen of no persistent authentication. 3. It does not need a second header, so it is somewhat simpler.
