For others that may be looking for the answer, the "timeout_absolute" and "timeout_inactive" parameter values are included in Isilon's response body, though they are not configurable via RAN and it is recommended to keep them at their default values.  Thank you, Richard Bicknell
Hello,  When I read the RAN Reference, it seems that I can specify timeout_absolute and timeout_inactive when creating a session:  Body: {  "username": " ",  "password": " ",  "services": ["platform" | "namespace"], "timeout_absolute":value, "timeout_inactive":value }  But I always receive a response with timeout_absolute:14400 and timeout_inactive:900, no matter what values I set, e.g: {"services":["namespace"],"timeout_absolute":14400,"timeout_inactive":900,"username":" "}   Is that actually not supported?
