Hi, This is Nikhil from Linkedin Engineering.
A Key Rotation feature has been added to TLS session tickets; details: http://comments.gmane.org/gmane.comp.apache.trafficserver.devel/2084 At present, this feature relies on periodic execution of traffic_line -x to reload new keys. However traffic_line -x reloads entire configuration, and so has a much wider impact than needed. In order to address this concern and to localize the impact of reloading keys, we would like to propose following approach: ATS will schedule periodic continuation which checks the session ticket key file. The reload interval will be records.configurable. If the session ticket key file has been modified, ATS will reload the keys from the file. Please comment on the proposal! Regards, Nikhil Marathe
